Stumbled across this freebie on the Giant Eagle website:

Buy five hot or cold beverages in a cup from a Giant Eagle Market District, GetGo or Express store and your sixth one is free. It appears you do need a Giant Eagle Advantage Card, because the site says your purchases will be tracked on your card and you don’t need to save receipts or carry a punchcard.
