There is definitely no shortage of weigh-and-pay frozen yogurt establishments in Lower Merion Township. At these popular sites it is not uncommon to see fro-yo enthusiasts purchasing over a pound of frozen yogurt with toppings, intended to be eaten in one sitting. Because there are so many in such close proximity to each other, these businesses must constantly come up with promotions to draw customers to their frozen yogurt rather than their competitors. On Wednesday, Kiwi, on Lancaster Avenue in Haverford, will be offering eight ounces of free frozen yogurt to all customers, all day. There is no doubt that many patrons will walk away still having spent money.
