Chiangi,
I also received HK49s without name and with name throughout this year. I believe HK49s without name came to me with 1K kit (may be wrong?).
Anyway, HK49 is not very useful for non US members. I have 8 HK49s with various expiration dates. I will not use them and I do not want to trade them in the Coupon Connection. Rather, I would like to give them to someone who really needs it for handicapped people's trip or something like that. Or UA can let us exchange them with something else which is usefull for us, especially for Japan residents.
