Hey Francis:
I haven't ordered much in the last few months, and I have not become a member at Tower Hobbies, but when I placed my last order last week (web site) I had the option of entering a promotional code which gave me a $20.00 discount. The promotional code was in the homepage. I don't know if this appears in your computer if you become a member, or what the limitations are (once a month? one per household? not for members??), but how about splitting your next $7000 purchase into 35 $200 purchases, getting $20 off on each one, and free shipping for being a member? Not likely, I guess.

BTW, you are spending way too much money on this hobby!! (envy, here)
