I did a search on Black and Decker and filtered by in-stock items at my local store to see if they had any of the B&D items that were posted . When I did, I stumbled on this. When I did a search on SD, it appears to be an all time low, at least as posted here.
My store seemed to have a bunch left, but brickseek shows pricing all over the place in my surrounding area.
I had to add the trimmer to my cart to see the lower price. Enjoy!
