Target offers the Evenflo High Back Big Kid Amp Booster Seat in Carissa, model no. 31911432, for $28.80 with free shipping. (Amazon charges the same.) That's a buck under our mention of a different color from last spring and at least $8 less than you'd pay at a local retail store. It can convert to a backless booster seat and features adjustable height, a removable seat pad, shoulder belt positioning strap, and elastic cup holders.

Of note, it's also available in Sprocket, model no. 31911431, for $29.60 with free shipping. (Amazon also has it for the same price.)
