I get tired of hearing people talk about all the bad with eBay. I don't work for eBay, but I haven't had issues. If you are selling a legit product and someone buys it, there should be no problems. If the high bidder doesnt pay- you are out nothing. You just notify eBay and then re-list. It's safe to say Apple (the BMW of electronics) gets you about 65% maybe 70% back of your original purchase price.
I sold a nearly 3 year old MBP 13" for $700 on eBay. Paid $1100 for it. Do the math, its a no-brainier!
Obviously this assumes you have used eBay and have a positive track record, but $200 or even $275 for my IP3 32GB+ cell would be a ripoff!
Obviously Best Buy has to make a profit and that is why they are doing this....
