Can’t find this carrier anywhere!!

I have six guinea pigs that I bring with me when I visit my parents. Three are housed in one cage, two in another, and then a single housed pig because he’s an asshole, lol. When I bring them to my parents, I’ve been carrying them in those “starter” cages you get at pet stores, but they take up a lot of space in the car and they’re big and awkward to carry. I went to the pet store and came across this carrier - it was the only one on the shelf, and it’s perfect for my guys as the car ride home is only an hour and a half, so they aren’t in it very long.

The issue is that I need another one but I can’t find it anywhere! It’s a Petmate underseat carrier designed to go under airplane seats. It was discontinued on Chewy and I’ve been searching eBay and Mercari. I’m just wondering if anyone has seen these or is maybe getting rid of one similar to it? I would happily buy it!!!
