Why Your Membership Matters Here
Costco’s deals are for members only. A Gold Star membership costs $65 a year and an Executive membership $130 a year, with 2% back on most purchases for Executive members. A single big-ticket deal, like the $100 off the SimpliSafe kit, covers more than a year of Gold Star fees on its own.
Our Take
Costco does not wait for Black Friday: the strongest home and tech discounts land in the first wave, starting today. The SimpliSafe kit at half price and the $1,200 off the Samsung fridge are the standouts. Food and gaming shoppers should wait for November 16.
Best for: members planning a big-ticket home or tech purchase before December. Skip it if: you are not a member and only want one small item.
Costco also sells a Whittard hot cocoa advent calendar this season. For subscription box offers, follow our Black Friday subscription box deals roundup.
