where do you see it's up to a limit of $1000?
i only see "Limit 10 Staples Gift Cards per name/address/household". Each rebate form, you will get 1 Staples Gift Cards. So based on their written terms, I can buy 10 x (any number of visa/mastercard gift cards) x $200
Good luck with that.
The way I read it, and the way most read it before this "glitch" was exposed, is 1 rebate for a $100 MC/Visa purchase is worth a $15 GC. Limit is 10. $100 x 10 = $1000.
