WorthMonkey, FinalCost and Vote in my poll.

Here's an interesting tool to help you determine how much your used stuff is worth: WorthMonkey. It basically takes a sample of other items's value from from the net and calculates a fair price. Here's a write up about it at lifehacker. I think it's really cool.

While I'm sharing cool links: ever order something on eBay from the States, and you want to know how much duty you'll pay when the thing crosses the boarder and ends up on your doorstep? FinalCost.com helps with that.

"This online calculator will help you estimate the final cost of purchasing items from the USA and having your order shipped to Canada."

And look! There's a poll on the right hand side of the screen: please vote.
