If you are doing a lot of craft shows I would suggest you average the sales tax of all shows you do, add that to your price and round to the nearest $.50 or $1.00. We used to do all of our prices, i.e. $5.95, then add sales tax at the shows. Every show we did we had to add a different sales tax percentage, then add all orders, add sales tax, carry all the change, etc. We finally went to doing it the way I suggested above and now all we have to carry is bills and quarters. It is much easier to figure sales, we don't have to carry all the change, and people seem to like the idea of having the sales tax already included in the sales price. Try it, you'll like it!
