This pricing floor seems like pure BS and I doubt it came from Stern.
Quoted from Pdxmonkey:Buy your game from an out of state distributor, no sales tax.
This works well till you get a fair tax letter from your state asking to account for every out of state purchase and pay tax for the last three years. I was flagged by some shipping document. Anyway, I would still go the out-of-state route to avoid tax, but it's a possibility it could catch up with someone.
