Does Best Buy sell Fit Bit wrist bands in the store?

I did see some. Probably better selection online.

Yes they do

They do have limited replacement band on the shelf, but will also show you a selection they can have shipped right to your house or be available for pick up.

I seen them at the one in Portland..

I think so

Yes, they used to sell that when i went there last year. Not sure if they still do.
