Someone outbid me on the "cactus-shaped rubber stamp'' listed on Ebay

Mr. Big Bucks, I hope you're happy. I had my sights on that attractive little cactus-shaped rubber stamp on eBay. It was going to be one of my promotional gimmicks, and now it's gone --- all because of you. The bidding war was ferocious. I lay down $4.50. You upped the ante to five bucks. The next thing you know, you jacked up the price to $6.50. Whoever you are, you are shameless.
