If you buy out of state you avoid sales tax. Cointaker & Game Exchange are reputable dealers with fair prices and CGC distributors.
Curly's Little Shop of Games is a CGC dealer in Florida.
I would ignore the MSRP and dealers will include shipping and other incentives although this is drying up somewhat due to manufacturer request.
AFM & AC/DC are both highly rated games so you can't go wrong. KISS is a fun game but I would only purchase if you really love the band.
