Can shop offers like this run out of available quantity?

https://www.swagbucks.com/shop/in-store/48277/armor-all-advance-auto-in-store-offer/

When I click on "upload instructions" and see several products to choose from, but none of them involved with this offer, does that mean I can't go buy the stuff and get the 1500 sb anymore?

I sent this in as a support question but nobody seems to be answering so I figured I'd try here...
