I am writing this letter to tell you how unhappy I am with your product. I bought the juicer after seeing it advertised on television. I love fresh-squeezed juices and wanted to make it at home. The [___] of your product seemed reasonable, and I was very excited to receive my order in the mail.

The sentence is about how much the juicer cost to buy. “Price” means the amount of money charged for a product, so “The price of your product seemed reasonable” is the natural phrasing. “Amount” needs more context, while “rate” and “value” do not fit this meaning as well.
