American Express is not blocking my large transactions but rather sends me warning email. Recently I purchased Furnace, AC etc for $11k - no problem, only warning message. American Express is also better than Citibank Visa in foreign travel. Visa requires me to call them (otherwise card does not work), while American Express traces pattern of purchase like Airport, another Airport one town then next town instead. Credit Companies protect themselves since I'm not responsible for unauthorized charges as long as I haven't lost my card. Some companies make it very difficult for user suspending any "suspicious" transactions sometimes going too far.
Kjweisner, you would not be responsible for those charges anyway - no need to be grateful to anybody.
