Hi,
As in the subject, is it possible to let customers do arbitrary payments? Like in gift certificates for example. They just type in the amount and gift certificate is created. This certificate is then put in the cart and the cusomer is then able to go to cart and buy it as a product.
What I am asking is; skipping the product-cart part and make an arbitrary amount of payment.
Is it possible? I couldn't see an add-on doing this.
