Hi,
does anyone know if the cart can offer a system that customers buy 'credits' for products listed.
Example:
1 x apple costs 3 credits
2 x apples cost 5 credits etc
1 credit cost £1 etc
Sorry you do not have enough credits in your account, to purchase anymore apples, please top up your account using PayPal or Nochex click here etc etc.
Cheers
Kroggy.
