How do they handle the sales tax?
Amazon charges me 7%.
so 700 dropped by 15% = 595 but add the 7% sales tax it is back to 636.65.
This is the reason I don't use purse as the sales tax hurts. Maybe I am wrong and they won't charge that sales tx.
That is very good question. Actually no idea.
Your discount comes after taxes is applied
From what I understand from the website and emails they sent me you say what you will pay for an item and it goes on a list for people with Amazon gift cards to accept. So the people that accept your bitcoin price are the ones who actually pay the sales tax and shipping. Could be wrong, but that is my understanding.
