There are no restrictions to what prices to set for your products. You can make your products as cheap or expensive as you think is appropriate. Keep in mind that making your products too expensive might dissuade customers from purchasing your products.
Print-on-demand and ePrint versions of the same product can be set as different prices. To set different prices for different options of the same product, please see the article on How To Change the Prices of My Products?
If you aren’t sure about how to price your products, please see our guides on pricing your Choral and Instrumental music.
