All I can say, is there is none at my local Lowe's. Benn back several times and finally there was a bag with a discount sticker on it. Bought, and will continue to check. Didn't know about TrueValue, may have to check them out, or maybe order some Wicked Good and have it delivered to my local Ace hardware, just to try them.
Currently using a Char Griller Offset, 2 UDS and a OTS. Continuing to look to add to what I currently have.
