Discount Coupons and Canadian G.S.T.

[josh_img]

We have a Canadian client who we've installed Discount Coupons (3.31) for. However it seems that the module doesn't know how to handle the Canadian G.S.T. (Goods and Services Tax), as the invoice will generate a sub-total, factor in shipping, display the discount code and then...nothing.

 

For example:

 

Invoice for customer NOT using a Discount Coupon

Sub-Total: $56.98

Canada Post (1 x 1.452kgs) (Regular, 2008-02-12): $7.69

G.S.T.: $2.85

Total: $67.52

 

Invoice for customer trying to use a Discount Coupon

Sub-Total: $46.27

Canada Post (1 x 0.506kgs) (Expedited, 2008-02-19): $7.69

Discount Coupon gckw2732 applied: -$3.70

 

 

Has anyone else run into this problem? If so, can you please advise me in finding a solution? Is there a more robust discount coupon solution that I should know about?

 

Any feedback is greatly appreciated!
