Stacking cashback? How is it done?
I've heard others talk about how the "stack" cashback offers...I saw that FatWallet has 3% cashback for J&R too.
If I click through from Discover's site and end up on the J&R page, do I then open a new tab and click through FW's website as well? Using this scenario, I would end up with 2 tabs both on J&R website.
Is that how people stack cashback?
