At Sam's Club they use Member's Mark, meanwhile Costco uses Kirkland, this is an easy way to tell where someone often shops. Costco has alerted their customers in Michigan and every other state in the country that they would have to recall a Kirkland product for safety issues. The product in question is a bottle of wine, Prosecco Valdobbiadene, that has shattered multiple times whether its being handled or not. The recalled product can be identified by the item number 1879870, according to the company. They are awarding full refunds to those who have purchased the wine but don't want any bottles brought back to the stores.
