As of 1-31-19 Lowes has about 67 options online from $32.34 to $2,271.02. They vary from light ones you can take with you traveling to heavier duty ones. Most of them seem to be aluminum. None are available in-store, but can be ordered and shipped to you or the store to pickup.
I have never seen one there.
I don't think so but you can always call the store or go on Lowe's .com to see if it is offered.
