I was making a 500+ mile round trip every weekend for 6 months when settling my Dad’s estate. I timed out stops at Panera’s every 2 hours along the way. I’d order for the next stop from the current location. I kept reusing the same tall plastic cups w/lids. I’d walk in, place my order for the next stop then fill a couple of cups with lemonade, iced coffee or decaf. You can have unlimited refills but only order Sip Club every 2 hours. I was getting 1 Sip Club and refills. I had jugs & a funnel in the trunk. Would empty the cups into the jugs and head to the next location. I kept some in Dad’s refrigerator for when staying there. At home I froze a lot of lemonade which I mixed with iced tea in summer. The closest location to me is an hour away so I usually can’t use cheap/free Sip Club but that year I got 2@ 3 month offers.
