Until April 1, if you type in the promo code "FREECOMICS" while ordering from Mile High Comics, you can get $10 worth of back issues for free (you still have to pay shipping). If you're missing a few UY issues, this is a good way to get some inexpensively. They don't have every issue for sale, but they do have a couple of the color specials and some colored Mirage issues:

Thanks for pointing that out to me. It's been ages since I've sent a check through the mail to purchase anything, and their shipping is pretty slow, but those are pretty good prices for the old Mirage issues.
