I bought the round ones for $6.95 ea. (Now that's reasonable...If Chevrolet sold them they would have been $20 each). I leave them in all the time and made a mating piece for my jack so it can't slip off or move around. They work great!
I've got the square ones. Thirteen bucks each or there abouts at the local BMW dealer (in stock). I leave mine in too. I thinks it more a matter of how do you get them out once there in?

My stupid jack puck didnt even fit the hole on my jack. Luckily I have a big grinding wheel and custom ground the tab to fit. The hockey puck would have saved me money and trouble.

I used a 3/8" x 2 1/2" eye bolt screwed into the hockey puck's flat side. I then flattened the eye-bolt a bit (by putting the puck and bolt into a vice), so the head was more oval than round. This allows me to insert the eyebolt end in the frame rail and twist for a snug fit.
I have accidently left them in after use and they've stayed on just fine, but I would strongly recommend against driving with any pucks installed, as they could do some damage if they fell out while the car's in motion.
Buy a couple of hockey pucks, go to Lowes or Home Depot and get a piece of PEX (black, plastic, flexible water pipe). The size is approx. 1" in diameter - but it fits snugly into the hole in the Corvette frame rail. Drill a hole all the way through the two hockey pucks with a drill (hole cutter, forstner bit, what have you) the size of the PEX. Shove about a 3" length of the PEX pipe through the hole in the hockey puck. When you press the part of the pipe that extends from the hockey puck it will fit firmly into the frame rail until you remove it. Very simple, very easy, very effective, very inexpensive - way less than $10.00.
