Hard-to-find gear

We were able to get the stroller we wanted in a discontinued color after it had sold out elsewhere and the shipping was really fast.

Service that saves the day

I had the NICEST person that assisted me and assured me it would arrive in time... I have never experienced that level of service in a long time.

Fast shipping

Glad to have purchased from a small shop after an Amazon order of the same item could not be fulfilled. Great customer service and quick shipping!

Legit, authorized store

After some digging and finding out they are actually an Uppababy authorized retailer... they definitely went the extra mile with their service.
