This is not a real product. It’s only for our customers to make up the difference. When you want to pay more charge for upgrading your skates after your order has been sent, you can pay here with the amount after discussing with our salesteam.
For examples, you need to pay $40 for upgrading your frames from Presto to Avant, you just put 4000 in quantity field and check out,because our unit price is $0.01. Then the paying is done. If you need to pay $30 for upgrading something else , just put 3000 in quantity field. Or you want to pay $56 for a set of extra wheels, just put 5600 in quantity field, and so on.
But this action should be done before the skates are sent out if you don’t want to pay extra shipping. If you want to buy accessories after the skates have been sent, you will need to order in our accessories district with paying additional shipping fee.
