Today is a great day. Mission accomplished !!
We went to the store about noon. Waited about 25 minutes for a sales person and was told none in stock. My wife said while we were there at least I should buy a shirt, which I did. I decided to ask my shirt salesperson if there might be any Birkins. He did not know. I did tell him as I told the original person, that it was a special gift for out 25 anniversary. He went over to the woman's handbag area and brought a sales person to me. He said he would speak with a manager and asked my wife what size and color she liked. She said either 30 or 35 in a basic or neutral color. He told us to stay in the mens area. Five minutes later he brought a box with a 30 Birkin in a taupe color(I'm not sure what they call it). It made my wifes face light up. What a wonderful way to finish our trip.
Thanks to all.
