Costco will soon do something it only does 7 times a year
Members will need to plan accordingly.

Costco is a unique retailer for a number of reasons. First, like other warehouse club stores, it requires that shoppers buy a membership to walk in the door (or at least tag along with an existing member).
Costco also specifically aims to offer the most competitive prices on the items it sells. And it won’t stock an item if it’s not happy with the price.
