You probably missed an excellent opportunity to grab some very popular Daz assets on sale for cheap a couple of days ago. A bunch of the Ironman13/i13 bundles were on sale for $2.99 per bundle. I do not expect that to happen again anytime soon...
There's a number of places you can check for Daz freebies. I've included four links at the bottom of my post.
Plus, of course, there are the freebies that are available through the Daz3D store, with a few new freebies appearing every couple of weeks.
You can actually manage to do a fair amount of stuff using just the freebies, but mainly those are best used to help familiarize yourself with the program, and maybe do a few nice renders in the meantime.
If you are going to be buying Daz Studio assets regularly at some point fairly soon, you WILL want to grab a Platinum Club membership. Right now, for non-members, they are 20% off (50% off for current PC+ members, but of course mine isn't due for another 5 months...), but I've seen higher percentages than that in the past (50% off used to happen a lot, 30% off seems to be more of the norm now).
The 'just' 20% off PC+ is probably a bit too steep, but if you plan on spending say more than $250 on Daz assets in the near future, yeah it may still probably be worth it, especially assuming that you wanted to take advantage of the current PC+ sale deals while they are still on.
If you already have a Daz PC+ membership, yeah definitely squeeze the life out of that baby - within your budget constraints, of course!
Between the additional freebies you get every week (often texture addons, but there's usually a standalone product or two in the PC+ freebies every week), and the additional discounts you get on everything, not to mention the two $6 coupons (restrictions apply), yeah for new Daz buyers it's a no brainer really, unless you are planning on spending very little on Daz assets - say less than $200-300 a year may be the point of diminishing returns.
Here's the text from a post I made a few months ago r.e. Daz3D sales and such (I've updated a couple of minor points):
Daz3D Store shopping tips
1) Don't buy Platinum Club at full price.
30% discounts on PC+ club memberships happen every month or so, sometimes the discount is bigger. 50% off of PC+ used to be fairly common, not so much lately.
If you do significant amounts of Daz shopping, yeah get Plat club, you'll earn enough discounts to offset the membership price fairly quickly (generally within the first month for me, but then I regularly do a fair amount of Daz3D asset shopping.)
There are weekly PC+ freebies, and of course the two monthly coupons ($6 off DO's, $6 off of 18), which are nice too. The weekly PC+ freebies are somewhat hit and miss, but sometimes some really cool stuff ends up as PC+ freebies.
2) USE THE GIFT CARDS!!!
Gift cards go on sale at least once a month. The discount isn't usually all that huge (10-15%), but sometimes the discounts are deeper. After buying a gift card, you simply transfer the balance to your Daz store credit, which in effect translates to an additional discount on any items you are buying with said gift card store credit.
Not too long ago, there was a stacked discounts and coupon situation where the discount worked out to 32%, but of course you had to buy items from a certain prerequisite list to trigger the higher discounts (i.e. the buy-in). I'd consider this very rare, but if you shop in the Daz3D store regularly, yeah keep an eye on the sales discounts for gift cards when they are offered.
3) Watch for the steep discounts
40-50% off artist catalogs is rather common. 60% is a bit less common, 70% or more is unusual and definitely worth considering.
80%+, yeah this happens sometimes, usually on older items, and those sales are definitely worth looking into if you are looking to stretch your Daz3D shopping budget and are wanting to increase your product library with fun wardrobe items and such, assuming that you have the required Autofit plugins to use said items on newer figures.
As an example, the current PC+ sale that's been running for the last couple of weeks (since mid-October), and that should be wrapping up soon - yeah there are some real deals here, just gotta keep an eye on the sales.
4) The Daz Deals browser plugin
There is a Daz Deals browser plugin, which tracks the sales history of various items over the last year. While said graph doesn't tell the full story, i.e. when additional discounts are triggered with additional purchases, it can give you a pretty good feel for the 'deal' being currently offered on an item, and how often that item might go on sale.
It also has associated sales discount email alerts, which you can disable if you want, but these alerts, specifically the 'best deals' one can give you a quick heads up on sales on how good the discount on your wishlisted items might be.
5) Don't be afraid to submit a ticket for a price difference if an item you just bought goes on sale for a steeper discount. The Daz sales team will often give you a credit for the difference, as this indirectly ties in with the Daz return policy (i.e. Daz allows you to 'return' most items if you aren't satisfied, to a point).
6) Stacked discounts and Daz math
These are a
LOT more rare then they used to be, but occasionally you see situations where discounts from different sales can combine for a bigger discount, assuming the prerequisite items are purchased. The Daz Deals plugin will sometimes point out when these might be in play.
Daz math often applies additional discounts on the 'remaining percentage' rather than the full percentage. I.E. an additional 20% off of the 30% off (so .7 x .8 = .56, not .5). If you are looking to maximize your Daz spending dollars, yeah keep in mind these nuances with the Daz math...
I'm sure there are others, and maybe these should be moved to their own thread, but in the meantime, those are the 'biggies' for me.
As for Renderosity...
1) If you are a Prime member, you get more 'cash back' via rewards points than if you are not. Also, Prime members get better discounts on a number of (not all) items on sale, etc.
2) As a prime member, you get that 20% off one use coupon every month, and additional coupons often show up throughout the month. Of course, it doesn't apply to all items (some vendors do not participate in coupon discounts with some/all of their items), but every little bit helps.
3) Your Renderosity wishlist is a bit more important, as every so often a 'wishlist' sale shows up that offers 50% or more off of wishlisted items. Not quite once a month, but I've seen 3-4 of these between December and now.
Renderosity items often have smaller 'mega sale' discounts than say the Daz3D store, but oftentimes newly released item prices (with discount) are cheaper on Renderosity than they would have been in the Daz store. Plus there's the reward points...
Sure, the Daz store is absolutely huge compared to Renderosity's store, but Renderosity does allow more risque content, which a few of us here probably make use of regularly. And some of the Renderosity vendors do not have presences in the Daz3D store...
Then there's Renderotica, but I don't have a lot of experience with Renderotica sales, so I won't comment on those.
Other Places for Freebies!!!!
As for freebies, yeah there are a number of these out there, plus you can often import .obj's and such and use those, assuming that you don't mind assigning new textures to them as needed.
A couple of places to check for some interesting freebies:
You must be registered to see the links
You must be registered to see the links
(check freebies section)
You must be registered to see the links
(links to a bunch of freebies from around the web).
On these freebies, definitely check the usage rights. Some are personal use only, others allow commercial or unlimited usage.
Also, for HDRI maps...
You must be registered to see the links
This site has a bunch of 3d sphere environments that also provide suitable lighting in your scene, at least for Iray anyways, not sure how they behave in 3Delight). The site does like donations, but the HDRIs can be grabbed for free.
I'm sure there are other sources for 'legit' free assets, but this should be a good place to start. Google can also be very helpful when trying to track down free 3d models and such.
