Due to PayPal's new rule that requires sellers to absorb the 3% fee on any returns. We will need to charge a 3 % restocking fee for any and all returns / refunds. NEW POLICY READ!!! Buyer to pay shipping for  both ways for all returns.We will repair all parts and labor for no out of pocket cost to you except the shipping .For any refunds there is a 3 % restocking fee unless the item is exchanged which is easier for us often  since we have multiples of these in stock usually . Buyer will also accrue another 3% paypal fee having the money returned by using paypal if paid via paypal originally. (this new rule is because of paypal’s new greedy way of not returning the original fee back on returns/refunds and I regrettably have to bring this new policy to you the buyers.)The point is you will save a lot more money doing an exchange over doing a return
