Don’t Buy- Spices
Spices, just like ground coffee, do not have the longest shelf life. Even though they would not expire or spoil, they do lose their flavor after a certain period of time. If you cook for 2 to 4 people on average, you should get smaller jars instead. Italian restaurants are the only ones who should get them in bulk.
Buy- Vanilla
Even though spices lose flavor after a little while, vanilla tends to retain its flavor. The large bottle of vanilla extract at Costco is a great investment. If you like to bake cookies, you will not regret this choice.
