Amazon cuts up to 63% off select Allen Sports bikes and accessories, with prices starting from $10.78. (Although the sale states up to 30% off, we found deeper discounts within.) Plus, Prime members qualify for free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, shipping starts at around $5.) A couple of best bets:

• Allen Sports Hitch Mounted 5-Bike Carrier for $158.29 (pictured, same at Walmart, $142 off)
• Allen Sports 2-Child Bicycle Trailer and Stroller for $182.81 (same at Walmart, low by $7)
