Walmart offers Liar's Dice for $15.98. (Amazon charges the same for Prime members.) Opt for in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $5. It includes four shakers and four sets of five dice.
Walmart offers the Don't Tip the Cows! Game for $6.88. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could find by $12, although we saw it for a little less four days ago (since expired). It includes 18 stacking cows and a travel tube.
