I think coupons should be addressed as well

i.e at the moment if you add something a 10% discount then it takes it from the ex VAT price (if you have VAT added)

Its not a problem if you are selling just in the UK as you enter your prices inc vat anyway but if you ship worldwide you have to enter your prices ex vat and then x-cart adds on the vat.

this causes the above and so when a customer thinks they are getting 10% off the price they aren't they are actually getting 10% off the ex vat price and the customer feels cheated.
