I found these on clearance at my local Lowe's (specifically the Greenwood Village location in Colorado.)
The Shelf price had them listed for $24.98, but after checking out I realized I was actually charged half of that only $12.49!!
Upon realizing this I went back in and purchased 4 more units and when I left there was still 5 additional units remaining!
The checkout guy checked and told me there were multiple units at surrounding stores as well.
So YMMV but it's certainly worth checking your local Lowe's given these things normally go for around $60!
