Like everyone else, I have favorite websites and would like to share them.
Shopping:
Where to find a cool lucite cane
This site sells items made from electronic, including computer, circuits boards. I like the coasters and the key chain. And now they have a business card holder.
Have you checked out Cafepress? It's a market where people sell personalized items. Also, a lot of groups sell fundraising items at this site. There is a store that sells items for sweepstaking enthusiasts and one that sells non-coffee items for coffee lovers -- I think it's called Coffee Geeks.
I know I have added links to several ecrater stores, but there are hundreds of stores that site. If you are looking for a specific items (like frog things) go to the main page ecrater page to search all the stores.
Two other places to find homes for things you no longer need - or find things that you DO need!
This link might take you to the Minneapolis page, but you can select your area. It's a great way to find home for items that are too heavy to mail. I have found homes for old computers, books - sometimes for free and sometimes for a small fee. You might find more expensive items listed here than at the next site. Think safety - do not go alone to meet with the seller or buyer.
Here you enter your zipcode to find the freecycle group in your area. In my town they have a yahoogroups.com forum where people can make one of three types of posts: Offer, Taken, Wanted. I have just listed a few things here. I have seen people ask for things as simple as 3-ring notebooks. A range of items can find new homes through this service.
