Normally I'd suggest that people (including myself) hold off on buying a lot of stuff until the annual Daz+ fall sale in October/November, but since they keep throwing us bones in around the $1.99-ish category, I've been buying stuff from that part of the sales recently. There's been some interesting items in those parts of the sales, at least for me.
But yeah, unless there is something you ABSOLUTELY need, the current sales aren't bad, but if you have the Daz Deals plugin installed, as usual pay attention to the 'recent best' price point that's now appearing on the product pages, and of course the 'price point tracker over the last year' graph.
I will note that some Perry Walinga stuff is currently on sale, if say you are looking for a place to fire off your $6 off of $18 coupon. He makes some interesting environments/aircraft/boats/etc. if you've been looking for a change of pace with such things. Like this spa that I just noticed...

I wouldn't recommend such things for systems with tiny amounts of VRAM though. Sure, you can hide a lot of the stuff that's off camera, but that'll only take you so far.
Anyways, if you end up buying three items from PAs in the associated sale, you get a slightly better discount (around 65%-ish, plus whatever stacking discount you may have going on atm). PW stuff in particular rarely gets steep discounts, so this may be 'about as good as any' as far as opportunities may go if you have need of something...
Here's the 'view all artists' link for the part of the sale I'm referring to:

That's my two cents!
