It seems I cannot locate an online seller of Road to Legend that is not "sold out". Anyone know when or where I'll be able to order this expansion?

Best bet is to see if you can find some minor shop that still has it around. I managed to get mine from some tiny shop less than a month ago, and even got a discount, since noone was buying it.

or try ebay.com ------------------------------------>

Where in the world are you located?

I know Amazon.co.uk also had a copy when i looked, but wouldn't ship it outside of the british isles.
