I am selling stuff on eBay, can I post on craigslist that I am selling on eBay?

Absolutely not. Craigslist is for local, face-to-face, cash transactions only. Posting your auctions there is rude and violates the TOS, and would get flagged off. The more often your ads are flagged off, the fewer flags are needed to flag off your ads until it gets to the point that they come down in seconds.

The point of eBay is to deliver prospective buyers. If you're posting your auctions correctly, and you are offering items that people want for a fair price and have a good feedback rating, you won't need to post anywhere else. If you're not posting your auctions correctly or have these other problems, you can wallpaper the planet with ads for your listings and they still won't sell.

The bottom line is to stop looking for places to spam and start looking for ways to improve your listings.
