I need to develop a discount coupon site similar to [url removed, login to view] or [url removed, login to view] or [url removed, login to view] or [url removed, login to view] that enables vendors upload their in-store free and printable coupons with expiry dates and codes that may be scanned at the till. Should have a 'shopping cart' type of function that allows consumers add selected coupons after which they may print their selections at once. Target market is rather cynical about online spending however with time it is anticipated online coupons will be made available. Consumers may sign up to receive offers from vendors. Vendors should manage their content.
