Shopping at Costco is fun, but some items there are better deals than others. If you are not careful, you can get dazzled by the presentation and easily spend more than you intend. The following five items are great deals at Costco. They are items that you can't buy anywhere else for the price or the quality. If you regularly buy these items, they make the cost of your membership worthwhile.

Organic Quinoa

Although the price of quinoa has risen lately, I can't find high-quality organic quinoa in bulk at a better price than at Costco. In my local store, the price for a 4 lb. bag fluctuates between $12.99 and $16.99. Because the quinoa manufacturer processes the quinoa to remove the saponin, the bitter-tasting coating on the quinoa seed, you can cook the quinoa without washing it first, a major convenience. By the way, 4 lb. of quinoa goes a long way.

Earthly Choice Premium Quinoa

Organic Quinoa from Costco

Quinoa is a grain that is high in protein, naturally gluten-free, and a complete protein. Surprisingly, it is a source of calcium, which makes it an option for those who are lactose intolerant. Quinoa is also a source of magnesium, which is difficult to get from food.

Frozen Organic Blueberries

The frozen organic blueberries that Costco carries are a great deal. I buy a 4 lb. bag for about $13.00. Frozen blueberries are the best kind to buy because they are usually picked when ripe and then frozen to keep their nutrients. You can keep them in the freezer for up to 9 months or longer. Fresh blueberries are expensive, especially when not in season, and you have to worry about using them before they go bad.

Because blueberries are so small, they warm up to room temperature quickly. 10 or 15 seconds in the microwave thaws them enough to add to cereal or yogurt. On a hot day, eat them right from the freezer and let your mouth thaw them.

Recent studies have shown that freezing blueberries does not destroy the antioxidants[2]. This is great news because blueberries contain loads of antioxidants.

Organic Spinach

Spinach is another super food that you can buy at Costco in bulk at a good price. However, you need to check the sale by date and verify the freshness. If the edges of the spinach leaves wilt or appear torn, don't buy it unless you intend to cook them that day. Spinach loses nutritional value over time[1], so buy it only when it looks fresh.  

Spinach is full of antioxidants and is a rich source of vitamin C, K, and E, and many other nutrients. 

As a small child, I asked my mother for spinach because I wanted muscles like Popeye. Unfortunately, she bought canned spinach. As you can imagine, as an 8-year old I was not impressed with canned spinach. It tasted like wet cardboard, so I decided to forgo the muscles. Maybe the story would have been different if she provided a fresh spinach salad with vinaigrette dressing. Well, maybe not. Regardless, as an adult I love fresh spinach, in salads or cooked.

Wild Alaskan Canned Salmon

I prefer wild salmon over farm raised. Costco has a great price for canned, wild salmon that tastes pretty good raw or cooked. It comes in a 6-pack of 6 oz. cans and usually cost around $13, well below the price at my local grocery store or online sources. Unfortunately, wild caught salmon is becoming scarcer, so I expect the price will rise. That is why I stock up now (canned salmon lasts for several years). I keep an emergency supply. Just don't forget to include a can opener with your emergency stash. I learned that the hard way during the last hurricane.

Cameron Hughes Wine

A neighbor who is a wine connoisseur alerted me to this next deal. Cameron Hughes wines are blends sourced from California wineries and sold directly to Costco. Cameron Hughes gets the leftover lots of high quality wine that the wineries normally would sell to manufactures to blend in with cheaper wine. Essentially, for $10 to $13 per bottle, you are getting wine that normally retails for $50 or more.

Unfortunately, Cameron Hughes wines are not a regular item at Costco. I see them only sporadically, so you have to watch for them.

Have fun shopping.
