Walmart offers the Allen Sports Deluxe Trunk Mount 3-Bike Carrier for $34.94. Opt for in-store pickup to dodge the $5.99 shipping charge. (Amazon charges the same for Prime members with free shipping, although it's on backorder.) That's tied with our mention from last August, $15 off, and the lowest price we could find. Features include a tie-down system and 15" carry arms.
