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.
You guys see the FF Premium on Kijiji for more than NIB?! COVID times are over and supply has caught up to demand. They'll be making foos for years to come and there are probably NIBs available at distros. Totally doesn't make sense.
Whether it makes sense or not, ask whatever you want, the market will set the price. If the price is not in line with NIB or current market value, it will sit there. The problem in most cases is that if you put a reasonable price on it, guys will come in and offer you ridiculous lowball amounts because they think you are desperate.
