Change prices according to user level

Hello

So I am new to WordPress and need a bit of help. The company I help run has an online store and we have rep all over the country. What we are trying to set up is that when a rep/retailer registers on our site as a user and logs in, they see a different set of prices. Is there a Plugin i can use or is there a way I can change the prices according to the user level?

Thanks for all the help!
