The extra discount on subscriptions is not surprising. I think it is part of "Grand Plan" to turn daz+ subscriber to premier. When they reduced the price of d+ annual subscription at the end of June and extended d+ existing subscriptions by 3 months, I was happy as mine was about to be finished and was extended to October... And now I have a d+ subscription that will end in a few weeks. and I have to consider whether I renew or turn to premier alternative.
I am probably not the only one, and I tried to quantitatively assess the interest of premier. Of course, it is based on my tastes and shopping habits, but it may interest you.
So concerning the benefits of premier vs daz+.
Coupons: the $6 d+ or $10 premier DO coupon is great and you can get this way almost free DO assets. 1er gives you a direct extra $4/month.
The 6/18 or 10/25 coupon is more questionable and one cannot consider it as an extra money/month. Indeed, to use it at its best, it must be
combined to other discounts and frequently the best offers already require the use of a coupon. For instance, with last month sales, you could not have at the same time the 30%/artist and the D+/1er coupon. Only advantage, 10/25 is 40% off, which is very good, and it is not affected by the "minimum price after discount" threshold. But I do not consider it as an advantage larger than $2/month compared to the d+ coupon.
Discounts: extra discount is always good (on DO, plus, etc), but I already have a large library, and I mostly purchase items with a big discount. With the new "minimal price" policy of daz, frequently, the threshold is reached and having any extra discount is useless. I do not purchase a lot and the benefit is not worth more than a couple of bucks per month.
Gifts: when signing to premier, you get a shitload of free items. Seems great. But most are just characters addon (like Betty Boop for Catwoman 9). I rarely use genesis 9 and generally do not have the base character, they are without product page or a decent set of images, which IMHO makes them almost unusable. TBH I already have waaaayyy too much chars, and I consider these chars just as a library clutter (and a negative point for 1er subscription!!).
Besides that, a free bundle/month is great. Not a big fan of these G9 bundles, but I could purchase one for, say, $4-5, depending on its content, but probably not every month. Let's say it's worth $3 per month.
Extra tools for DS: I already had purchased several of them before they are turned to premier only, and having some tools that disappear from DS when you stop your subscription, is not very appealing. So $0.
Tokens: the 1 token/$5 purchase is very interesting. Alas, most of the very interesting sales (fast/quick grab, fixed price sales) are not token sensitive. More, I never really missed tokens while being daz+. I always had 8 tokens when doing big purchases. Maybe I could have used more tokens when purchasing only a couple of assets, but I do not think that the overall gain will be more than a few bucks per month. Lets say $3/month.
So to summarize daz+ vs premier:
Extra cost (with the 25% discount) Daz+ $50 1er $150, extra cost $100
Extra benefits: per month $4 (DO coupon), $2 (PA coupon), $2 (extra discounts), $3 (bundle gift), $3 (tokens)=$14/month or $168/year
So, it seems interesting and accordingly, I subscribed to premier, but YMMV.
