Simply put, if you claim a Blingtron gift package all your characters on your entire Battle.net account are locked from obtaining the gift package for one day. If you have more than one World of Warcraft License on your account, you can by-pass this. This also works for Blingtron 4000.
Instructions are simple:
1) Log into each account at the same time
2) Find or place a Blingtron
3) Open the interface so you have "Complete quest" button up on each character
4) Complete the quest on however many multitudes of accounts you have (this may be easier if you have a multibox program)?
5) Collect and open
6) Profit
Apparently you can't use your own Blingtron?
This still works.
