Visited a World Market (formerly known as Cost Plus World Market) in D.C. today - one of the displays below. Based on their website this chain has 260+ stores. The Yowies display are right as you enter the store, along with other kids toys and novelty items. They had been restocked over the weekend as advised by the staff, selling for $3.49 and expiry of Feb 2017. There were 3 of these display stands which seemed to house about 6-10 cartons per stand.
US Patent number on the capsule: 5,925,391 and 6,099,872.
