Several weeks ago I went out and purchased all of my stuff to set up my binder. I went to Staples because they were having a deal where you got 50% in whatever you spent mailed to you as a rebate. Now, I'm thinking the cashier didn't enter my purchases under my card. Can I take the sales ad, my receipt and my Staples card to the store to have the manager check on this? I also bought a ton of stuff to set up my home office so the rebate should be a significant amount of money. Anyone else buy stuff during this rebate offer and gotten theirs yet? Thanks in advance!
