Pricing

|

activerecord

Hi all,

I have a personal project I'm planning and I came to a small hurdle.

I want to have an item with price that will be the default for all clients/users. However, in my business I have some clients that are grandfathered in to some special pricing. In the case of these grandfathered in cases, I'll manually plug their special price in my admin section. Then all they will see is their special pricing while the regular users/clients see the default price.

What is the best and simplest way to design the back-end for this?

FYI - I'll be using rails as my framework.

Many thanks!

-Tony
