There was a Strait Patent corkscrew on ebay listed a couple of days ago, and oddly it had received no bids. Now typically, someone would have bid right away. When this happens, it is a dead giveaway that someone is trying to get the seller to add a buy it now; as after there is a bid, one cannot do that.
The item was in my "watch" list, and I popped on ebay this morning, and there was a BIN acheived. It was pricey for me, but the last Strait that I saw sell was in the 1200 range, and Ken sold the one on his site for 1400. I hemmed and hawed for 20 seconds, and decided I better act before anyone else saw it.
