Through 4/24, Walmart is taking up to $100 off popular Britax car seats, strollers and more at the Britax Baby Event. A best bet is the Britax Frontier G1.1 ClickTight Harness-2-Booster Car Seat in the Red color which drops from $329.99 to $234 with free shipping. It's the lowest price we found by $30 (compare to Amazon). Note that you'll have to enter name and email to view some of the prices, because the drop below manufacturer prices! Sales tax is charged in most states.
