Dremel Engraving, Sanding/Grinding & Cleaning/Polishing Kits $3.50 each @ Walmart YMMV

Was at Walmart picking up a clearance B&D Grinder posted in another thread.
Found a bunch of other clearance tools, including these Dremel accessory packs.
Currently $5.50-$8 online at Walmart and Amazon (add-ons), but even cheaper in-store at $3.50-$4 each.
