I use some Covergirl items and buy them at the DG, because they are generally cheaper. I used the LA Color as a teenager, and it was OK for a dollar, but their lipsticks and glosses feel kind of grainy. Still, for $1 it's worth a try.
If you'd like some other cheap makeup tips, you can also use Vaseline as a lip balm/gloss, and it's a decent lash-lengthener if you don't like mascara. I've found that this is a good way to save money. A 6 oz tub of Vaseline can last me for years.
