I just started my Shopify-store and I am still working on it. I have a question regarding payment; what I am looking for is when someone has added the merchandise to the
shopping cart and they are on the checkout page, I don't want to capture payment using skrill, klarna or something
like that, I want to add a form which they submit, either if this is done in Shopify itself or if I could link to an
external link, is this possible? Thank you very much!
