New harnonica

It's time for me to buy a new harmonica. Could you recommend a seller?

Here is the problem. I ordered a harmonica on-line at Guitar Center in Santa Clara, CA. When I came to the store for pick up, I expected that the harmonica would be in a sealed cardboard box, but the box was unsealed, so I did not take the harmonica.

In a couple of other local stores they sell harmonicas in plastic harmonica cases, which are unsealed either.

I expect that a harmonica should be sold a sealed cardboard box.

Is it a correct assumption?

Thanks in advance
