My worst rebate experience was actually with Staples but it wasn't an easy rebate. I mailed in two rebates totaling $100 on two Canon printers. I waited a few months and hadn't heard from them so I called them and they said they hadn't received the rebates and they told me to resubmit them. I resubmitted them and waited again for a few months and called them back and the said they didn't receive them this time either so I was given an email address and told that I could submit them there, waited about a week and still nothing. So I reported them to the Better Business Bureau and I got a call from Staples a few days later. The lady that called was really nice and she apologized for my trouble and she seemed really upset that this could have happened to me so many times. I faxed her my rebates and received a $100 check in about a week. So it all turned out fine but if I hadn't filed with the BBB I don't think I would have ever gotten them.
