How do I order 1 post card

We used to do single postcards at $0.99 each but the cost of printing, postage, and the fee the credit card company charges ended up costing more than what we charged. We decided that the $8 multi-card package (10 postcards) was the only way to do it. We've been around since 2012 and the postcard/holiday greeting card package is one of our best sellers.
