There was a discussion about how to handle scenario when merchant adds product with a custom price to order in which identical product already exists.
So:

1. Our main goal is to merge identical product rows (maybe in 1.7.8 or later, but not for 177)
2. That means we cannot handle different prices for same product

The solution for 1.7.7:
We check if order already has identical product. If it contains identical product, we don't allow to change product price anymore, but leave the existing product price instead. (in future we will want only to increase the quantity of existing product)
And if merchant updates the product price in the list, all of identical product prices should change.

@MatShir please correct me if I'm wrong
