If you go to UC Coatings web site, click on online purchase, enter your country and zip code, then select the product and size of container, quart, gallon, 5 gallon pail, you'll get an instant quote of the price.
I did one and the price for a 5 gallon pail was $47.50.
Your hardware store is marking it up some, I guess.
Why pay more threw a middle man?
