What I did was when I was placing my order for my SportMaxx was tell the lady on the phone at Tower was that I had an e-mail from them that gave me a discount but I had accidently deleted it. The lady then went to someone else and got a code for me. My code was for $20, but the code she used was for $25. It wasn't a lie, I did delete my code, but I wasn't about to tell her it was for only $20 instead of $25. The people at Tower are great to deal with.
