What's the most cost-efficient way to accept payments on my website? American Express will be the card of choice. Average sales order ~ $100-250. I am only in Alpha stage so I don't want to pay Braintree (or others) $80-100 / month, right off the bat (bootstrapping! )
Is PayPal my best bet?
Again, I will be receiving payments from corporate credit card holders via my website.
Does anyone know of any alternatives?
