OK last winter this was a big deal at another board about Tower codes and it got out of hand.Some of towers codes are meant for one time use and others are just a price break.

I was a tower member long ago(like when the net was just starting) but since it ticked me off that anyone on the net could get to the great deals while not being a member I never renewed.As a memeber you would get a list of stuff (among other things) that is marked down for whatever reason and there was some good deals but later on anyone on the net could get them which was lame and made membership useless.Now I see that there are some items on discount that require you to be a member.(DUH it looks like tower has found out why most people were not paying to be members)
I know there is a code for an additional $5.00 off and a code for a tool set and I'm sure there are others but I dont follow what tower hobbies does that close.
