I have said this many times already but here it is for the last time. They have a flawed system and we all know this. If you want to get back at them use this to your advantage. Look at post #4 in this thread: http://www.flyertalk.com/forum/miles...ping-mall.html. Was this just a fluke or can it be duplicated over and over? Use the same technique that was used against Costco and Sams. They have hundreds of retailers that I am sure you can find some that it will work against.
