It has worked but when people were abusing coupons sometime ago on downloads it would go to research and then they would ask you if you wanted to remove the coupon or cancel the order. Have not heard of that happening lately since the Chinese coupon hackers went out of business.
So assuming the $25 off online coupons will work on the website, what I'm planning to do is purchase 10x of the Kaspersky software using my brother's staples rewards number (different name, different address). However, another question arises regarding whether it's safe to use my own Ink Bold card to pay for the order (and hence my own billing address) or does that create a risk of merging accounts? Thanks for the help.
