Update on previous thread on Gift Certificates:



Sub-Total: $5.00

Flat Rate (USPS Flat Rate Shipping): $5.00

98101 SEATTLE 9.00%: $0.90

Gift Certificates: -$8.17



Total: $4.56



In order for the Gift Certificate to calculate, I have to set the sort order after local sales tax. When I do that, the sub-total, shipping, and gift certificate are doubled.

Sub Total = 10.00
Shipping = 10.00
Gift Certificate = -16.34
Sales Tax = 0.90

Total = 4.56

Does anyone know why this is happening? Can you help me out?
