KLKMCRAIL
This popped up on my facebook, and its an offer for 3% (up to $15USD) off rail passes for Europe, Japan, South Korea, etc.
Should be useful for those travelling and waiting for rail pass discounts. Every little bit counts right? The long expiry of this deal means that you can use this without trying to time the 3 month validity limited (eg Japan)
Only catch is that you have to use the code and a mastercard (but that is fine for me with my Bankwest card)
