We want to add a product that the purchaser can enter in the value. It is our physical gift card that we will 'value' and ship when fulfilled. Even thought the product will be called a gift card on our site it won't act/function like the gift card apps I have looked at so any app offering this functionality would work. My thought is this would be similar to someone doing a fund raiser and any amount can be entered? would love to find an easy solution as we prefer not to have to offer 'set' value gift cards.
