That and on the price tag it has 2 lines. The top one is the price we paid (we code it by adding 100

) and the bottom one is the selling price. I am about to get a point of sale system to make it easier and would like the exact amount. I think there is still a system, example:
Here is one order in front of me-
subtotal before shipping $157.56
shipping charge-$10.50
Total-168.06
so just a rough draft-round up to 158 and devide 10.50 by 158 to get .06646 so each dollar of product before tax would get added .06646 so a $20 product would actually cost 21.33? I know I'm very close but want the exact amount (I know I'm picky but times thousands of small items sold equals alot

)
