You pay through QuickBooks (Intuit). Your card is not stored on this website.
How you pay
After you send the order here, you pay with QuickBooks. That may be an invoice I send to your email, or a QuickBooks payment page. Card details stay with Intuit.
By paying, you say you may use that payment method and you agree to the total — the pieces, tax, and (if you chose shipping) fragile packaging and UPS.
When a piece is sold
A piece in a basket is not sold yet. It is sold when QuickBooks shows the payment as paid. If payment fails, the piece stays on the shelf.
Classes
A class form is a request. Your seat is held after you pay the amount I send you.
Mistakes and fraud
I may refuse a payment that looks unauthorized. If I find a clear price or tax error, I will write you and correct it.
Currency and tax
USD only. If your bank adds a fee, that fee is yours. I collect sales tax where I must.
