Very simple silverstuck. Go to www.usmint.gov and click on shop online. Once in that area of the site you can set up an account.
Yeah I believe a 1/10 Buffalo may be going on order from them tonight seeing they are discontinuing them.
You can call them at 1-800-usa-mint if you really want to. I try not to do that if i can help it. Make sure you have your item number.
Because they produce so many junk products that people complained. If you order something from them, you will be on their mailing list, and you will get their catalog. You also might be able to request one.
They are killing the 4 piece sets, the fractionals (1/10, 1/4, and 1/2 ounce) and are totally discontinuing the collectors version of the uncirculated buffalos. http://www.cointalk.org/showthread.php?t=43559
