If you would like add a warranty for peace of mind you can do; either daily or by unit (for engines etc) as indicated on our price list. You should add the "Warranty” amount to the "Price". This means if the part does not work and you want to return it for credit - all you have to do is come back to the store with your receipt and marked part within the warranty period and you can come out and get a replacement part OR if you cannot find the right part when you come back you can receive an In Store Credit for the value of the part that can be used for any part that UPickIt sells. Please note that we cannot give our customers cash back on these warranties.
