Ledger.com has another opportunity to purchase the Ledger Cold Wallet, this time at a 20% discount. The offer includes ONLY wallets in Ruby Red color. The promotion runs until December 23 this year.

Buying Ledger from my link we both get an additional $10 each in BTC :) So if you don't have your cold wallet yet, perhaps now is a great opportunity to buy one.
