Goodwill Shill bidding Internet

 I've bought a substantial amount of karat gold and sterling silver jewelry on shopgoodwill.com, over more than 5 years.  Most of my transactions have been positive, in that I bid my amount after researching the item, received the item(s) in good condition, promptly. 

That said, I've been shilled.  By someone.  Or maybe just a "playful" false bidder.  One example was a gold pendant, brand name, that I've seen on retail web sites, and which I really wanted.  I bid for example, $75.50.  Bidding was in one dollar increments.  The opening bid was $5.00.  So I made the opening bid.  No one else bid on the item.  I was beyond joy that this gorgeous item was going to be mine for $75.50. 

The last half hour or less, before the auction ending time, I watched the bidding go up in $1 increments.  Okay, I figured someone was testing to see how much they would have to bid to beat me by $1.  They got all the way up to $74.00.  I was watching like a hawk, and prepared to spend "just a litle bit more".  At that time, I showed as the high bidder.  Just one dollar more than them.  Had they bid $75.00, I'd have not won the auction, as I'd have not been at least one dollar more than this "shiller".  But they stopped.  I had my figures entered, and was ready to submit, in those last few seconds, but no, they never went further. 

Bottom line, I got my beautiful jewelry, and a very substantial mount off even retail on sale.  Goodwill got more than the $5.00.  Is this right though?  I'd have bid the amount of $75.00 or a tad bit more, had there been a reserve.  I don't begrudge the Goodwill the "profit". 

But I begrudge the way in which it was done.
