I was super excited to see this!! Amazon is offering a 2-year subscription to Redbook for $10. After you add it to your cart and hit checkout, $5 will be deducted giving you a 2 year subscription for $5 ($0.21/issue)!!
Don't want 2 years worth of Redbook? Snag a 1-year subscription for $3 (after automatic $5 deduction during checkout) here. Sweet!
