    I cannot understand the coupon discount calculation.

    I have a coupon set to apply 10% discount, we have products in the cart which total £59.90 which includes 20% VAT, the shipment fee is £0.00 so the cart total shows as £59.90

    When I apply the coupon it gives a discount of £5.39 - this is not 10% of the total nor is it 10% of the total without VAT included, can you advise

    Versions are:

    Joomla 2.5.8
    Virtuemart 2.6.6
    AwoCoupon Pro 2.3.5
    RuposTel OPC 2.0.274

    The discount make no sense. I think it is a caching problem. Please try this:
