I have had this add on working for a while but a few orders have come through that are smaller than minimum value. I noticed that if you add to your cart and it was below minimum value of £100 then you would get the warning in the shopping cart and the checkout button was not available. BUT! If you then continue shopping but then click on the CHECKOUT button it will allow you to checkout. I do have the FEC mod installed. Is there something that I am missing here??
