Yeah, I'd imagine they did that too. They have a whole aquatics section now which looks very similar to a lot of online aquatic sites. I'm guessing someone is just using their name to sell stuff.
When I ordered mine it showed instock, the next day it was listed as backordered on their site. After two weeks they sent me an email saying it was backordered and that they'd let me know when it was back instock. The very next day I got an email saying it was shipped. I was upset about the wait, but overall, the product came and was cheap.
