The German Xbox site is currently running a promotion where fans can get consoles up to 150 € off as long as they meet one requirement: having a high Gamerscore. The way the promotion works is that you request a voucher based on your current Gamerscore. So if you have 150,000 you get 150 € off your console bundle. 20,000 gets you 20 €, etc. The promotion is only available for German Xbox Live accounts and only for console bundles.
