When I check out, using a 10% off coupon, the system seems to calculate the discount wrong:
Sub-Total: $69.90
Regular Shipping (Regular Shipping): $14.95
Discount Coupon: SHH : -$7.34
Maine Sales Tax 5%: $2.80
Total: $80.31
The discount should be -$6.99
I can't seem to figure out where the discount is coming from. $7.34 is 10% of what exactly? It's not 10% off of the sub-total, it's not 10% off of the sub-total plus tax, etc.
Has anybody else experienced this? Any help would be greatly appreciated!!
