I have an WP e-commerce online store and since July 2011 I have been having so many dramas with my WP e-commerce coupons just not working. The discount works within my site but as soon as the transaction moves to Paypal, the discount is not retained and the full price is charged.
Any coupon with a numeral discount (eg. $50 or 30%) will not work. However, if I select the "free shipping" option, the discount works.
They were all working perfectly before this. And as you can understand, coupons are an integeral part of our business.
My web developer has upgraded to WP e-commerce 3.8.6, which said it had fixed this problem, but it hasn't. He has tried everything but we are both at a deadend.
I am using WP 3.2.1.
I have read quite a few posts with other people having the same issue. As you can understand, this is increasingly frustrating that one minute they were working and now they are not working. Please help!
