In fact, you should think twice about buying olive oil in clear plastic bottles — like Kirkland Signature olive oil — which is a big no-no when you're looking for packaging that blocks light.

Its bottles of extra-virgin olive oil generally sell for a very reasonable 41 cents or less per fluid ounce. But as reviewers have attested, you get what you pay for with this brand.

This Brightfrom set has two 16-ounce BPA-free plastic bottles. Unlike most olive oil bottles made from glass or stiff plastic, these squeeze bottles are flexible enough to grip and pour with one hand.
