Walmart continues to offer the Allen Sports Deluxe 2-Bike Spare Tire Mounted Rack for $29. Opt for in-store pickup to drop the price to $27.78. That's tied with last week's mention and the lowest price we could find now by $18. It mounts onto a wide range of externally mounted spare tires and features 15" carry arms, individual cradles with tie-downs, a padded lower frame, and 70-lb. weight capacity.
