A best bet is this Women's Irregular Pink Chocolate Apron (pictured) for $9.95. (Update: Coupon code "FATHER30" drops it further to $6.96.) With $4.93 for shipping, that's the lowest total price we could find by $27.
Note that these aprons are minimally to moderately flawed (they may feature restitching, loose seams or pockets, or minor printing flaws) and all sales are final.
Update: Better yet, apply coupon code "FATHER30" to cut an additional 30% off the sale price.
