My favorite reason to go to Fred Meyer is the play land. You can drop your kids off for one hour while you shop. I have two boys, 2 and 3 years old, and shopping with them has recently become extremely difficult. It's so nice to be able to drop them off and not have to worry about wrangling them in the shopping aisles or worry about them screaming.
They love the play land too. When we announce it's time to go grocery shopping they always ask first if we're going to Fred Meyer so they can watch a movie (their favorite activity in the play land)
Fred Meyer has definitely gotten most of my grocery shopping business lately for this reason alone.
