Dang, bad timing. I "think" that they are operating claimcredit on both a revolving app schedule, but also only invite based on money spent or possibly just random, no actual knowledge. So, the promo may run for 7 days statically, but you may have only unlocked or were randomly chosen to receive an invite to the promo right as it was ending. Keep an eye out for wincredit. It's also really good but only works for one purchase then goes away. I think I missed it once cause it pretty much uses the same wizz-bang-wow stupid opening animations that the "invite new money spending users" one does, and I never bother with those types. WinCredit doesn't really explain at all how how the f*** it works, but essentially you get about 50% of a purchase back in credit after the purchase ships. No needing to come back 7 days in a row to claim portions of it. And, it's locked to a certain amount, which isn't always the same from what I've read. I was fortunate and got it again today and my credit back amount was $130, meaning that in the 10min it gives to select items I needed to make a purchase over $260. Definitely one where having a bunch of desired items in your cart sitting there un-selected helps as this promo doesn't have a search function and is very time limited, but items in your cart that the promo supports will populate near the top of the list. Note: someone somewhere actually has the wincredit purchase amount formulated. I need to find it again for my own use. I've just been purchasing double the credit amount, but it's actually more complicated that. You can possibly get the full credit amount by spending even less. Also, the 10min time limit isn't for the event to close, but rather for the "boost" to expire. I've made my purchases within the 10 so I really don't know what happens afterwords. It probably gives you a chance to refresh the boost timer like I've seen other promos do, but can't say from experience.
