Crazy coupons

[Napier]

Hello,
We have created a coupon code to allow all customers who are given the code £7.50 off their next order. Is there a way to limit the coupon code to one use per user ?. At the moment the code can be used over and over again by the same user.

Not properly.

You could potentially create a javascript routine to place a cookie on the customers PC when the voucher code has been used and use that to prevent the voucher code being reused. They could still use it again though from another PC or by deleting the cookie.

PS. The other option might be to change the codes each month. This would also encourage the customer to use it before it expired.

Thats probably the only way and it sounds technical. Is this easy to set up, bearing in mind I can only just write my own name.

Cheers

Yes, it will be technical.

This page gives you the code to set and test cookies. http://techpatterns.com/downloads/ja...pt_cookies.php

You'd then need some code to intercept the form submit and either

a) block the submit if the cookie is set.

or

b) set the cookie and submit the voucher code form.

It could work quite well but the easier option might be the limited lifetime voucher codes.

Thanks for your help Mat. The limited liftime sounds like a plan.
Many Thanks
