Graco Nautilus 3-in-1 Booster Car Seat Only $99 Shipped (Regularly $140) – Great Reviews
Hop on over to Walmart.com or Jet.com where you can score this Graco Nautilus 65 3-in-1 Multi-Use Harness Booster Car Seat for just $99 shipped (regularly $139.99)! 
This top-rated car seat can be used from toddler to youth – it secures your child in a five-point harness from 20 to 65 pounds, converts to a belt-positioning booster from 30 to 100 pounds and also becomes a backless booster seat from 40-100 lb!
We have these seats and they are great. I love how you get a long life out of them. Fair warning though, they are bulky. So if you have a slim vehicle, they take up a good chunk of space. I drive a RAV4, and with two of these in the back, it leaves little room for the “seat” in between. It basically can just hold books.
Thanks for the honest review Jenna! Good to know how large they are!
Does anyone know how heavy these seats are? Hard to life and move around if you need to take it out of the car? Easy to install latch?
