Wow, this still works? Amazing. This is like the Second Coming of the savings bonds. I haven't done it yet but will definitely start so I can stay gold with HH. Sorry for being rude and not reading the whole thread but how much total dollar value can you buy per person/address?
The best thing would be to back up about 10 pages and read forward, you'll find a lot of current information about the coin program. I don't blame you for not wanting to read the entire thread. Things have changed from the start.
