I am looking for a place to buy a bunch of Fitrite backflow preventer covers. These are an insulated bag that velcro together to wrap around a PVB or RP to prevent freeze damage from a quick over night freeze. I have bought about 12 through out the year and want to buy about 15-20. My plan is to have them embroidered with my company logo & phone number. I want to give a few away to valued clients, and sell a few more in the spring. I am able to get them for $20 ea from my local supplier, that is already reduced from my regular price. but I want to try and find a better price if possible. Any one know where? I tried searching for them online but came up empty.
