Over and over again. They have to buy a new Phoenix Oath at the original retail price for it to work. For instance
The original price paid $100, + they paid $8 for the oath at 8%.
They get a new piece for $50 and if they want to cover the original piece it is going to be 8% of the original price, so they would pay $8 for the warranty. This would cover $100. So they pay $58 to get a new piece replaced and to have a new warranty to cover that same piece. They can do this over and over and over. If the piece is no longer around, they can get another one that is the same original purchase price.
