that's the right tag, but the tag gets a lot of posts so maybe when you're checking you're pushed off the page already? I user that, #fr and #flight rising sales and #fr sales, I'll also tag what breeds they are and if they're neon wings or bright wings, I don't know if that actually helps but I do it just in case.

Also make sure you're putting all the info on your posts too, like the gender, colors, genes, RTB days, price, etc, and list how the people can buy them from you and your username on every post.
