If you use the B&H Payboo card for purchases, be sure to check your invoices. The other day they offered the Vello screen protector for sale. I was supposed to save on tax and placed my order with that card. What I noticed is the correct item came with my name on the invoice; however, the order number doesn't match the original so I was charged sales tax. My online order shows the tax was refunded, but since this is a different order number, I'm not sure what happened. They are closed so I'll have to wait - but I"m sure they will make good on it. It's only a matter of $0.78, but if anyone makes large purchases, no one would want to pay tax with that card.
