Will resolve 'yes' if Costco announces they are raising the price of either their Gold Star membership, currently $60, Executive membership, currently $120, or Business membership, currently $60. 

Will resolve at year-end or upon announcement of a price hike, not upon the price raise going into effect. 

For example, if Costco announces they're raising the price in November but the price hike goes into effect in January, the question would resolve as "yes." 

The news must come from either Costco, via an official source, such as their online newsroom,

, or a reputable news outlet relaying the news from Costco. 

Stories speculating on a price hike do not count. 

Will resolve to 'no' if no price hike to any of Costco's three membership plans is announced by year-end.
