I think we all know their products are great, but for me, what makes this particular store great, is the service. We recently went in looking for a carseat attachment for our BOB stroller. We found the item we were looking for but before purchasing an associate pointed out that this particular model only fits newer strollers, built in 2011 or later. Good to know - saved us some cash and a return trip since our stroller was either a 2008 or 2009 model. The associate then called the stroller vendor (BOB) on our behalf without us even asking him to, to see if there was another carseat adapter sold somewhere else that was compatible with an older BOB stroller.
Maybe it was a slow day and the associate was bored, I don't know, but I really doubt it. We've had similar experiences in here before. Bravo REI. Love this place.
