I see that Apres.ski and apresski.es active on the net, although the later a clothing site.
Sometimes, I take a sale, just to keep the inventory moving. I too had a few ski domains. Never sold any and eventually dropped. Do the best for yourself.. this is only my opinion.
What's your asking price? How far apart are you with this $1750 offer? How long have you owned it? How many other offers have you received on the name?
