Fits perfect in the Prius and holds your groceries from rolling around on the way home. The cost was 12.95 at walmart. Wow the 8way volvo seat sure is bigger then the stock oem seat.
I like to use the plastic tote bins with the folding top lids that you can buy at Lowe's or Home Depot for around $5 each. Two of them fit nicely in the back of the Prius with a little extra room on the sides. At least with the plastic totes, if a milk jug or soda bottle explodes on the way home, I can just hose out the tote rather than dealing with a saturated carpet nightmare.
