Amazon offers Prime members UNO: Great Pumpkin Charlie Brown Edition for $5.61 with free shipping. (Non-members can get free shipping on orders of $25 or more; otherwise, shipping adds $4.50.) That's the lowest total price we could find by $12. It comes in a collectible tin.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
