The website membercost.com is a phishing scam and is not affiliated with Costco Wholesale. It uses a survey format to lure users with the promise of a $750 Costco gift card in exchange for personal information. Costco has explicitly warned customers that such offers—including those for free products like ice cream makers or large shop cards—are fraudulent attempts to steal financial details or identity information.
