Monday nights are good for starting then ending an auction .

Definitely put as much information as possible about each item and have a few photos of them.

If you're not in a huge hurry for them to sell, give Gumtree a go because it's free. I've sold HEAPS of things through Gumtree and have been rapt not to pay! eBay's fees are becoming ridiculous when you have to factor in PayPal fees too (also owned by eBay). Also, prams are very hard to sell on eBay (unless they are a currently sought after brand), so Gumtree is a good option.

Good luck
