Branding/naming confusion with http://celeryproject.org threw me for a loop. 2% of revenue on top of existing payment processing fees seems steep. I guess convenience has a price and this will be great for shops that want to get going quickly and are not price-sensitive. Seems like you are self-selecting for small payment amounts. If I had a $100 item I'm not sure why you should get $2 as opposed to 20 cents on a $10…
Wait this isn't the same as the celery task system? Yeah I was super confused as well. Probably not good to name something the same thing that has basically the same target market.
