I've always used GTC. About once a week I look at the listings ending for the next week or so, and remove the ones that don't have many views and/or have been on there too long. Those things get rotated in with antique mall stock, or put into garage sale or donation boxes. That way, the things that shouldn't be relisted, aren't. And it makes room for new listings. I take a pro-active approach to my listings, and I currently have over 1500 items listed. It's not hard. I sell vintage and collectibles, so it doesn't matter if it's at the top of the search list or not, there's usually only a few others, at most, of the same thing. I guess order does matter if you're selling something there's ten thousand of, which is probably a bigger problem than GTC.
