I've used TCB for about 3 years and have received about $400 in rebates. Their rebate percentages used to be significantly higher than competitors such as Ebates and Mr. Rebates, but no longer. Also, I have submitted several claims in the past for rebates that were not posted, and nothing ever happened. In contrast, Mr. Rebates and Ebates will give me the credit if I forward a copy of the invoice. For that reason, I have decided not to use TCB unless they are offering a really high rebate, and if I am willing to take the risk that it will never post.
