coolstuffinc, a fairly well known site in the board game and hobby community, has Escape From 100 BC on sale today for $14.99
full disclosure, I have never played this myself but on board game geek it rates a 7.32
this is $38.99 on Amazon, and I think regularly $39.99 on the coolstuffinc site
shipping is not included, I think it's about $5.99 depending on your location. I wish I had a more solid number, but out the door in guessing you will be at about $22 total
I don't post a lot of deals but this one seemed like a good deal for a good game if you have an interest. I think I'm picking a copy up for myself at this price.
