Split it
See Ticket adds PayPal's "Split It" function.
See has partnered with PayPal to make ticket buying for you and your friends even smarter and pain free, using their new feature 'Split it with PayPal'. Split it with PayPal helps you split the costs with friends when buying tickets for the group, helping you get paid back easily after checkout by sending each nominated person a "Pay Now" button in email so that they can pay you back for their portion.
