It seems to me that he's not even getting his money back. I paid just over $50 with tax from Petsmart, then added the grommet for the blow off tube and the spigot on the bottom, probably around $7 if I hadn't taken them off of the old 6 gallon bucket then add the airlocks at around $1.50 each. He probably has about $117+ in them. So yes, he over priced them, but not by that much, and it will save someone the trouble of drilling the holes. Now if he scored the sides at the seal to make it more cleanable (so you can take the top gasket off), that alone would make it worth the price. Just my 2 cents.
