AMEX user has his limit reduced for shopping at Walmart*?

[Racer X]

"When we would drive cross-country, we routinely would start to have our Amex denied, and we would have to call them and convince them that our card was not stolen. Now we've gotten in the habit of calling ahead and telling them our travel plans. A pain, but I guess that's the climate we live in now."

I do that every time I travel outside my state. they call it a travel advisory. You specify the date range, and area of travel. The last thing I wanted was my card being declined in Budapest, and being stranded.
