Avoid bulk buying these 8 foods - it could cost you more than you save

Cooking oil/olive oil

This might seem like a great bulk buy, but it has a shelf life of only six months, so unless you're frying for a large family every day, It's best to buy it in smaller quantities.  Olive oil generally lasts longer than regular cooking oil, but after 6 months the healthy antioxidants decrease by about 40%.  

Baking powder

If you don't bake all the time, you might want to skip buying baking powder in bulk, as it only lasts up to six months to a year. The difference between baking powder, baking soda and sodium bi-carb

Beer

Did you know that beer only lasts for 3-6 months? No, neither did we! So, you should only buy this in bulk if you're having a party!

Spices

If you love spicy food, you could be forgiven for loading up on spices at a good price. Spices can last for up to 3 years, but the flavour will decline over this time. They also need to be stored properly away from heat and moisture (so ironically, your kitchen isn't the best place!). A better idea is to buy whole spices and grind them as you need them. Alternative uses for dried herbs and spices 

Brown rice and whole grains (such as oats and quinoa)

Because these foods are high in oil, it makes them very susceptible to spoilage. Only buy what you think you can finish in six months, and make sure to store in an airtight container in a cool place.

Nuts

Nuts also have a high fat content and last just three to six months in your pantry.  

Flour

Regardless of whether It's whole wheat or plain white, flour attracts moisture, and it can quickly turn rancid. White flour does last longer than whole wheat, but unless you are a baking fanatic, your bulk buy could end up in the bin.

Coffee beans

If you are a real coffee lover, the best tasting cup of coffee is made from beans that have been roasted within two weeks of drinking, so avoid the giant bags. Buy smaller bags of beans and grind your own.  Things around your home that will make your garden grow
