Promotion voucher being applied twice to cart


I think I am experiencing the same problem as Mike here:


It appears to happen when a customer applies a voucher to a cart and then subsquently adds another item to the cart.

Interestingly, if you make the Maximum discount the same or less than as the discount amount the voucher doesn't get applied twice. If the limit is any other amount (or blank) then the discount is applied twice.

Screenshot below shows the discount that should be applying £10 to the cart total.

I am also getting the rounding issue with the voucher when applied pre-tax (VAT in my case). Entering £8.33333333 for a £10 voucher sometimes calculates at 9.99.

We'll certainly take a look.
