New to this forum so please go easy on me. I have a problem and not sure if this is the right forum to post on but here goes.
I have been given a promotional code for a website and I want this to be protected so that only people who have paid for this code can use it. Is there anyway this can be done ? Obviously there are sights across the net where codes are just pasted left, right and centre and it is vital that this only goes to people who have purchased it.
1) The user logs onto the site
2) The user sees a offer he wishes ie.10% off Amazon.
3) The user purchases this offer and recieves the promo code which he can then enter at the checkout.
The problem is he could paste this on any forum.
ALSO....I want this code to be only useable once.
PLEASE HELP !!
