Which credit cards give best rewards for big box purchases?

[Will F.]

Hey guys I do a lot of large purchases at the big box stores- home depot lowes etc.

I was wondering if there were good rewards programs for them. I know you can go to the pro-desk at home depot when you make a large purchase, but is there a better way?

Any other ways you get discounts would be helfpul!

I saw there was a citibank card for home depot rewards but it doesn't have a very good return.
