Thought Ordertree.com was part of Lowes. It is not! We learned the hard way that a wrong Greenworks lawn mower part we ordered could not be returned to our local Lowe's store. Lowe's in-store customer service (who never heard of Ordertree/Lowe's) called Ordertree on our behalf and was on hold for over 1/2 hour and once finally connected got hung up on several times. After lots of researching Lowe's in-house customer service found a return form that needed to be filled out electronically to get a return approval #. We went home and filled out the form thoroughly but kept getting an error message. On Monday we tried calling Ordertree.com customer service for assistance and experienced the same long hold time as our Lowe's store did and also got hung up on. It's clear Ordertree.com makes it as difficult as possible to do a return or even speak to anyone for help. Now learning there is a restock fee, plus no refund for shipping and then the extra expense for return shipping cost (if they ever answer the phone) we will just keep it and take the loss... of course itsc clear that is what they are hoping for! Don't make the same mistake we did and know what you are getting into!
