Pre-order codes for bonus items

Where can I find those codes? I am interested in the codes only, not the physical copy of those editions. I tried Amazon and Ebay, but either the codes were already used or the item could not be shipped outside US (I live in Italy).

Can anyone please help me?

I hate to be the bearer of bad news, but PRE-ORDER codes for sale on games that came out in 2005, 2006, and 2007 is only going to be a scam. Any pre-order codes that might be unused are either going to be expired or hacked, that's it.

a few years ago I was able to find the pre-order boxed for nightfall (the one that gives the extra character slot, if memory serves) at a local store, so there might be a few of these still out there. You can not get the codes from the on-line stores since the actual release of those chapters. You might be able to find some of the boxes unopened some places, but its been 8? years so they probably are long gone (stock usually doesnt stay around that long at stores).

i found an eotn pre order on ebay about 6month ago, had it delivered to a trustworthy friend in the US. they needed the expansion anyway and i got the code.

just have a real good look on auction sites is probably the best bet
