Simply answer - Of course you can. Not only should you have different prices for different plans, you should offer something equivalent to Bronze, Silver, Gold, Platinum, Diamond, etc. The name is not so important as is actually using a 3-6 Tier system. In the end, it is about what the customer wants. However, you should be able to do a back-end calculation and direct the customer to the Tier that is most profitable for your business. You just simply make it the most attractive with an "Irresistible Offer." If you want to be more sophisticated with this system, you can even offer add-ons within the plan itself. You do this by taking the customer through a series of screens with additional offers that are beneficial by may not be essential to the business needs. This is an opportunity for up-selling and providing what the customer wants.

Best of Luck,
