Sorry, I thought that was common knowledge. If you don't already have an Alexa device you can buy the Dash Wand for $20 and get a $20 credit on your account. As Amazon says "Essentially free with a $20 Amazon credit when you register the device." That sound like what I say to myself to justify purchases.
I'm still holding out for the Big Box to hit retail. I haven't seen the Queenies for sale anywhere for a reasonable price, so that seems like the only option to get them. Though my preferred OLGS doesn't carry either the Escape Zombie City game or the expansion, nor does it have a preorder for the Big Box.
We played the base game this past weekend for the first time, after leaving it unopened for half a year after the Christmas Queen Games Amazon Blowout.
Terrific game. Huge surprise. Co-players demanded to play it again, and again. Ordered this expansion immediately thereafter (still in the mail).
If you have plenty of games to play already (and who reading this doesn't?), I'd suggest waiting for a discounted Big Box version. For those less patient, I can't imagine the Queenies offering that much. The base game ramps up in difficulty very well and will be hard to wear out. The Chronicles expansion seems to offer a ton of content for the money, but we are loathe to try it until we've mastered the tougher difficulties of the base game.
I don't know what's more amazing--the price on this game or this Alexa tip for add-on items. I bought the expansion as a gift for my brother when it dropped to $9 from it's normal ~$17, and I thought I was getting a steal. Wow.
