Just a comment

The Leeson electrical motors that were ordered arrived quickly and without incident. However, shipping them individually in the Leeson boxes is risky. the boxes are barely taped and using FedEx causes them to be left whenever and where ever. in my case, they were left out overnite in the rain and now the boxes are roached. MRO processed the order promptly. This is a shipping comment, not an adverse business comment.

Great price and fast shipping.

Motor came well packed in double boxing. And arrived earlier than promised. Great vendor. I purchased this motor for a 2 x 72 belt grinder that I am building.

When will I be charged for my order?

Do you provide credit terms?

Can I get a discounted price? I am a reseller / government entity.

What is the return/warranty policy?

Can it be shipped today?

Does “Usually ships in 24 hours” mean it’s in stock?
