I went back to the sale on the last day. I had even set an alarm but set it for the wrong day so it never went off. I realized it about 5 minutes after the alarm was supposed to ring and went to the sale. They said that the chips were sold. AARGH! I figured that I was the only one who would be even mildly interested. Then as I was looking at the jewelry a lady came up to the check out with the chips. If I had been there five minutes earlier I may have been able to get them for myself. She said that her boyfriend had worked in Las Vegas and may be interested. I had purchased the one bag and it has two chips rated N and M so I did okay. But it sure would have been nice to get the other 4 bags.
