eBay has added a new feature (or at least it's new to me!).
Called "Map It," you can search for items near where you live (or anywhere, for that matter). The default setting is 25 miles from your residence.
You can occasionally negotiate with a seller to let you pick an item up instead of paying to have it shipped. I recently did that with a camera I sold. The buyer drove about 40 miles to pick it up. Saved him about $20.
