We are looking to add voucher codes to the site, so that when people go via the site we are able to track when they have made a purchase on an affiliate network through us and we are then able to carbon offset the any revenue we generate via the affiliate deals.
Users will be able to register and track how much they have offset via us.
They will be able to view all stores and add favourite ones.
[url removed, login to view] gives more of an idea of the funcionailty needed.
More details will be given in term of screenshots and proposed databse structure.
Test site is ready for you to develop on.
