This looks interesting a bit. I dunno how I ended up at this site, but I did. Looks like a bit of work to set it up though and merchant accounts are US-only: Stripe (https://stripe.com/). Quick n' dirty way to take credit payments online.

EDIT: Found We Pay (https://www.wepay.com/) as well.

Sheesh so many alternatives - I wish the internet would take them!
