It looks like the ones I got are no longer available and the link is to a different one and higher price. When I got these green ones they were $39.99.

This is the actual bed, but different manufacturer and link, so I cannot confirm if it's the same exact one, but it looks like it. Also marked more expensive.
That's also the thing with Amazon purchases. Company gets a few bad reviews, launches a new "company" and keeps selling the same thing. It's a roll of the dice.
