is there a cap on the amount that one can buy?
Nope. But i think theres a max amount of them you can use per ticket.
so i went and got themdo they always have these, or only certain times?its nice to get 2% back from costco and then points from the cc
Costco Exec members get 2% back on all purchases. Plus SPG is worth at least 2 cents.
its worth being the costco exec bec if u dont get the $50 (more then reg membership) back from 2%, then u can "return" the membership or theyll refund u the difference.also when i signed up they were offering $20 for new signups
