I'm a college student, strapped for cash, so I do the freebates at Eckerd and Walgreen every month. Yesterday I went to the Eckerd near my school and purchased some items available for freebate. I also purchased a cartridge for my plug in air freshener. On the way home from stopping by my mom's house, I realize I got the wrong brand cartridge for my air freshener, so I stop by a different eckerd to return it. I was buying a couple things after returning, so I didn't notice that the cashier not only gave me attitude but forgot to give me the receipt back!! How do I get a receipt for submitting my freebates?? Can I return the stuff I bought for the same items and use that receipt?
