Q: Is Saturday a better day to list things on craigslist, or are all days the same? ...I listed things on craigslist because of you, and made $30 in two hours!!
A: It definitely doesn't hurt to have your listing near the top of the page when people have time to browse Craig's List. (If you're new to this online classified site, each city's ads are broken down into categories, but each category is one long scroll of ads. As new ads are published, older adds slip further to the bottom.)
I've had great responses just about any time I've listed there. However, I think you will have a better rate of actual pick ups if you list near the weekend. Sometimes it can be a hassle to find a convenient time to meet. The easier it is for buyers to come, the faster you will get your money.
If an item doesn't sell over the weekend, don't give up hope. Buyers can--and DO--use the search tool to look through older listings. I just sold this LEGO table for $35 profit and a Hooked On Phonics set for $40 profit. Both had been listed for over two weeks before they sold.
