Is there a standardised approach to reward/discount websites

[Sonnenblume]

This is kinda a random question, but here goes. I've been tasked with putting together a staff offers website/cms in PHP, which will allow colleagues to access a range of discounts from various suppliers. I can think of many different ways of doing it, I was just wondering if anyone could tell me if there is a standard approach to this (i.e. what information to pass, variable names etc).

I know that many suppliers offer discounts across different staff sites so I'm guessing there is a common approach. While I'm only starting off with about 20 or so suppliers who will only be offering discounts on this site, I want to make sure I don't have to rewrite much of the system if further down the line it has to interact with a supplier who already offers a discount with a different reward site.

I hope this makes sense...

I would think it may involve a few new tables, including a price option table. Each product offered in this manner would need to have this price option type association as well as a buyer-to-price-option table. Buyers would need to be authenticated prior to visiting the product page so you would know which price type(s) to display for them.
