Three (3) weeks ago, I purchased a 20V 6ah Li-Ion battery on 9/17/17 for $80+ shipping. I emailed to follow up 5 times only to find out that the part is on 'back order'. First I was told (via email) that it would be delivered in 30 business days. Then after 3 weeks I follow up again and was now told it was due to arrive to their location from the manufacturer on 11/20 and it would ship after that. 60 days! These people didn't ever bother to show that it was 'out of stock' on their website - they just let me wait and wait until I finally sent them an email (and several more)- you know, there is no phone number to be found for OrderTree. Terrible - Don't buy from these folks! Absolutely terrible. I needed the battery for a chainsaw I had to cut down debris from Hurricane Irma - worst company I ever had to deal with. Never again. I ended up buying another small chainsaw from another company.
