My local Hobby Lobby carries Model Master enamels and arcylics (a few select colors in acrylics), Vallejo, and regular Testors enamels. They also have Tamiya Putty and Primer spray paint whcih surprised me. No Tamiya paint bottles though. :(
Funny thing, I usually print out multiple coupons and try to cash out each item separately. One time they did do it, last night they couldn't because it only honors 1 coupon per person per visit. So I went to another cashier to use my other 40% coupon. I bought 2 items - cashed them out going to 2 different cashiers. Hey, it worked though... LOL!
