I'm looking at buying a coin from a shop in California, where apparently, they charge 7.75% sales tax. Can I ask them to waive it since my state does not require me to pay sales tax? Edit: I Googled it and found that I had asked a similar question about Heritage back in April. I'm not sure there was a consensus, but I got the overall gist that, since Heritage does not have a presence in PA, they can't charge me sales tax. Therefore, I think that I wouldn't have to pay the CA sale tax...? @Treashunt ? @Conder101 ?
