I'm currently a Prime member, but I might let my membership lapse when it expires in a couple of weeks. I haven't uploaded images in forever, and the Prime forum seems even slower than this one, so those aren't very compelling. The discounts are the only draw, for me.

My Poser spending is somewhat erratic. I've actually gone years without buying anything (which was a waste of a Prime membership). Lately, I've been spending ridiculous amounts of money.

I might wait to renew my Prime membership until I want to buy stuff again. Which will probably be soon, but unlike the Platinum club, there doesn't seem to be an incentive to renew before your membership expires. You don't get a discount on the price if you renew while you're still an active member. So there's no reason to rush.
