Buy- Vanilla
While spices lose their flavoring, Vanilla doesn’t. You can buy a huge size of Costco’s vanilla extract, and it will be a great investment. You never know when you may want to do some cooking, so it’s better to have it lying around.

Don’t Buy- Tissues
You can clean up a sneeze with any brand of tissue, but with a cold, you will need a strong, tough quality that won’t break. You may be eager to buy a huge amount at a time, but you won’t bet on getting the best quality since Kirkland’s quality is not going to help you with a runny nose.
