I have two somewhat local CPAP stores I use - one is Corner Medical (Red Wing, MN - 45 miles) the other is Adapt Health (Owatonna, MN - 20 miles). Both are good. Corner was convenient when I was in Red Wing every other week for chemotherapy, but now it's a very long drive.

Fitting a mask properly is one thing that a skilled local provider can do better than an online outlet.
