It has nothing to do with cashing the checks. I had received letters and NO checks had been cashed. It is tied to the ADDRESS. Even using different names and different credit cards, and different phone numbers can do it if the address is the same. They say that their limit is 4 per 12 month period, although they didn't deliver my 4th, but when I called and added some foreign currency to the order, I got it. However my daughter who did not have 4 did not have her order filled (including foreign currency), no letter, just no sending. I will try it again by phone.
