Tom posts a $50 promo code (spend $50, get $50) for $10.
Other Members can then make offers to buy/use Tom’s promo code.
Tom accepts Sarah’s offer for $15.
Sarah escrows $65 ($50+$15) & gives Tom a list of items to buy.
Tom orders the items, then enters Sarah’s delivery address.
Sarah confirms receipt of the items & the $65 is released to Tom!
Sarah gets $35 off her order & Tom makes $15! Win-win!
