Walmart offers Twilight Struggle Deluxe Edition Board Game for $35. Opt for in-store pickup to cut that to $30.01. (Amazon has it for the same with free shipping for Prime members.) That's $3 under our mention from a week ago and the lowest price we could find by $17. It's a two-player game that takes approximately three hours to play.
Update: It's now out of stock at Walmart; however, Amazon still offers it for $38.69 with free shipping.
