Jump Zone Night'Sky Light-Up Sky Diver, Walmart YMMV, availability varies, low as $0.25, decent availability nationwide @$1
Saw this deal and immediately thought of how much I played with those cheap small parachuters when I was a kid. Checked brickseek around me hoping for some but unfortunately 50 miles for a parachute guy to play with the kids can't be justified. Looks like there's enough availability for many SDers to take advantage though. Reg price is about $5 at Walmart and target. No reviews, but I found their non light up model on Amazon with 20 reviews @3.9/5, and a YouTube video reviewing it against a similar toy (skydiver won). Consensus was that it was well-made, works well, especially from a balcony or other elevated spot, and rarely tangles. Kids also loved it.
