Quick question about coupons.com app.

If there's an offer for a $1 cash back and the item is BOGO at a store and I buy it, so I actually buy 2 but only pay for 1, would I get $2 back? More to the point, can you use the coupon multiple times on a receipt?

Edit: For anyone reading this and saying I made a mistake, yeah I just realized the Publix BOGO and the coupons are for 2 different sizes.
