Your overpriced items insult Craigslist MTL user intelligence
Shame on you, especially in terms of the profit you think you're going to make. Go buy an ad in the Gazette, Suburban, Examiner, etc., or if you want a profit, get off your lazy behinds and sell on eBay. That's your clientele -- not Craigslist community members. This is a virtual garage sale -- adjust your prices downward accordingly -- or don't post.
Nobody is buying your overpriced items, and you're polluting the neighbourhood.
