I just picked one up myself. There were plenty in stock. I haven't assembled it yet, but it looks perfect for my needs.
I was thinking about getting the 12 gallon 6hp one for $30 after coupon, but I realized there really was no need to haul around such a big shop vac. For the occasional use, 6 gal 3 hp is just fine.
Got a grount sponge too for $1.87 while I was there.
I also noticed that they carry Stoner's Invisible Glass. I haven't tried that before, but the reviews are always positive for it. I may end up picking up a couple more sponges, some SIG, maybe some
APC and use the $10 off coupon.
