Puppy,
I can be RELENTLESS when spending OPM (Other People's Money)!
This'll probably be my last run at this, and then I'll let you go!
OK, you mentioned you think it is too late since it has been over a month since the cancelled auction. If you REALLY do want this item, I still think it's worth a shot. You might even be able to get a DEAL, especially since you think the seller may have cancelled due to low bids! He may feel the demand for the item is not as good as he thought -- may make him more flexible on price.
Your e-mail can say, "I didn't get a chance to bid in your auction until after it closed, and I was hoping you might relist? Is it still available? Would you be willing to accept $XXX for it? If not, what amount were you hoping to realize for it?" or something similar. Open negotiations with a lowball offer, you never know the deal you might get!
I DO get the impression this item is more firmly in your "Like to Have" column than in your "GOTTA Have!" column! Either that, or the widget is not EXACTLY what you're looking for? Maybe missing some features that you'd like it to have?
Even so, it would still be an interesting exercise to run out the lead. If/when you get a response from the seller, no matter what the price is (unless it's what you offered!), you can always say "Thanks! That seems like a fair price, but no thanks. I was hoping to pick up the widget for less than that." or whatever.
OK, I'll let go of the issue now!
