Okay guys, I think i figured this one out. What sends off the alarms at Chase is not the frequency with which you buy the checks, but WHERE you are cashing them. Remember, these are Travellers Checks. So if you live in Dogpatch, USA and buy $900 worth of travellers checks then cash them the next day in Dogpatch, obviously you are not using the checks for their intended purpose. The Chase computers are probably programmed to pick up on the location of where the checks were cashed, which is why so many of you got cut off after just one purchase. The solution: you need to work in tandem with a trusted relative or friend who lives at another location, the farther away the better. This way you can order the checks and then send them unsigned to this person. They then use the money from the checks to order their own set which they then send to you to begin the process anew and avoid THE LETTER. I will be recruiting relatives to try this out and keep you posted.
