Hi guys, I want to make a real non-fake offer website where people can get stuff when they complete offers in return. Example: Someone want new shoes but can't afford or don't want to pay for them. That dude or dudette found out about my website and knows that they can buy shoes using points from completing my offers. He/She registers,logs in and completes some offers. When she made enough points from those offers, she'll buy a new pair of shoes. Question: How can I buy new shoes for them automatically when they have enough points ?
