Hot dog combo is sacred

Still $1.50. They've said it stays. I believe them.

Saturday afternoon is unusable. Tuesday at 11am, empty. Plan accordingly.

Kirkland is consistently good, sometimes great

Their olive oil is better than what I was paying twice as much for at Whole Foods. The bourbon depends on the batch — 2024 was rough.

Returned a 4-year-old vacuum

Stopped working, brought it back with the receipt I found in the email archive, got store credit. No hassle. People aren't lying about the return policy.

Membership pays for itself if you have a household

Family of four. The Kirkland staples plus three gas fillups a month more than cover the $130. Returns policy is the real hidden value.
