Can you freeze chicken salad bought at Sam's?

I've never tried freezing salads containing mayonnaise. I don't know how it will look when it's thawed as the mayo may separate and the celery may go soggy or mushy.
You can but you'll need to drain the small amount of watery fluid caused from the mayo after it's thawed and add a little fresh mayo to remoisture and reflavor.
