You can create different price points for the same product with our Price Variation feature. This feature can also be used as a way to create general variations for the same product, as you can create product variations with different names, unit prices, currencies, and costs per unit. 

You can enable Price variations for your products by going to Tools and apps > Products. 

Variations can then be configured from the Detail View of the Product in question. 

Once you add a variation of the product, you will be able to select this variation when linking this Product to a Deal.
