I think it would be nice to have the ability to deposit money to woocommerce site and let other people send credits to other registered users on the same store. Something like builtin paypal usable within the website.
The recepient of the credit will receive an email that say something like..
Your friend John Doe has sent you $100 credit to treat yourself at www.myshop.com
Thanks for this idea. We don’t ever do something as big as PayPal within WooCommerce but if you really want to send someone money you could send them a gift certificate with Smart Coupons: http://www.woothemes.com/products/smart-coupons/
