The fees alone will kill you. Also the fact you can never know if the bids are being 'artificially' increased, so factor in the cost of the bids + fees to see if it makes any sense and if the price is right for you!
Keep in mind, once they tell you to pick up, you have to pick up on those days - they won't accomodate as they need their space to bring in more stuff.
Finally, amongst many other things, if the game needs fixin', you're stuck with it.
Yeah, I'm not a big "sight unseen" auction fan!!
