We bought the free refill mugs. It was a great deal. We earned half our money back on each in just one visit. The each have a sticker on them. If the sticker isn’t there, they will not refill it. It is good only for pop and water refills. Specialty drinks are regular refill prices. You can refill them through the end of the year.
Our group bought 4 total. We got 3 different years. I assume they have a warehouse full of them and that’s why they are doing the promo.
