Sale prices and Discount issue
Whenever I put a product on sale why does a customers discount always overrule that discount?
Example: Product A is 20% off, if I scan Product A into a sale, the discount of 20% comes off immediately. But if I type a customers name into the sale after I scan Product A, and that Customer always receives a 10% discount, Product A automatically switches from 20% off to 10% off.
Is there a way I can override this issue from happening again?
