Buying and Selling on eBay

Buying and selling stuff on eBay can be a real headache. I've bought stuff in the past that looked like it was local, but ended up shipping from Japan - it took weeks, and then I got stiffed for duty when I finally got it.
I've been reading up on some eBay selling tips before I sell my old CD collection. No need for that anymore now that I have an iPod (also bought off eBay!) I might sell some of my old computer gear too. Hopefully I will make money from these sales so that I can buy a new mac book. Guess where I will buy that from? That's right - eBay!
