I have bought from them in the past and by the past I don't mean 5 years ago, I didn't pay Florida tax. That was the case no more the a year ago and that they charge tax is news to me. If they charge it now, oh well, you know who's to blame for that. It's doubtful this or any other ammo is going to come down much in price so you might just begin to add to your stash now rather than later. The price of ammo may moderate some but the tax will never, ever go away.I was looking at their selection too. They do charge sales tax though.
