 WHIO's Ron Otto reporting no word yet on what led up to that shooting. Disappointment for Costco members. The cost of a membership to the warehouse disc counter is going up for the first time since 2017. Starting September 1st, the Gold Star membership increases by $5 to $65. The executive membership will rise $10 to $130 a year. The good news? The price of the hot dog meal is staying the same.
