Does this Walmart stock and sell masks and snorkels?

Yes

Yes and they should be putting it out real soon. They've already started stocking summer items

Only cheap ones 4 kids... Try Academy

You might try going to Academy. Walmart won't have that until the summer.

Seasonal item. They will have them out early like maybe end of feb, for the upcoming spring break. Hope that helps

I believe they are seasonal

Most likely
