I've worked at Costco for 19 years. Here are 10 of the best things I'm seeing on the shelves right now.

I think the Optimum Nutrition micronized creatine powder could be a great addition to your routine, especially if you're hitting the gym.

According to its packaging, this powder can support muscle building and performance when used daily, over time, alongside an exercise routine. To use it, mix a rounded teaspoon of the unflavored powder into a shake or glass of water.

The Optimum Nutrition creatine powder is $20 at my location. 

Each box of the Pressed wellness smoothies contains 10-ounce bottles in acai-berry, strawberry-orange-mango, tropical, and greens flavors. The smoothies contain 100% juice and three to four grams of dietary fiber.

At my location, an eight-count package costs $16.90, which comes out to less than $2.20 per bottle.

As Costco starts bringing in springtime items, I think the Macsports XL folding wagon will be a hot seller.

This collapsible wagon has brakes for easy stopping, an inside zipper pocket, and an adjustable handle. The wagon can also hold up to 350 pounds and has durable, all-terrain wheels.

The Macsports wagon is $90 at my Costco. 

If you ask me, everyone should have the Cat Cube lithium portable jump starter in their garage or car.

This four-in-one tool has a few features, including a lithium jump starter and an air compressor.

The Cat Cube lithium portable jump starter costs $130 at my location.

I recently added the Turbotax 2024 federal e-file and state download to my shopping list.

These downloads are available in deluxe, home-and-business, and premier packages, so there's something for almost everyone's tax needs. Each package also comes with a $10 in-product credit that can be used for services like live tax advice or state e-file fees.

At my store, the Turbotax download packages run from $56 to $96.

If you're running out of freezer space, I recommend heading to Costco to check out this Midea product.

This freezer chest has two removable wire storage baskets, a front-mount temperature control, and an interior LED light. Best of all, it can turn into a refrigerator with the flip of a switch.

The Midea convertible chest freezer is $200 at my location.

If you're a fan of Mexican-style dishes, these Del Real tamales are a great find.

The tamales come with a cheese-and-green-chile filling — don't worry, they aren't spicy — and take less than three minutes to heat in the microwave. I also like that each serving contains 13 grams of protein.

At my store, a 15-count pack of the Del Real tamales can be found in the deli section for $18.80.

The Thomasville Wills oversize chair and storage ottoman both have ultra-soft furry corduroy fabric that's comfortable and chic. The chair, which measures 64 inches long and 35 inches high, has an extra-wide seat and two large pillows.

At my store, this set is $500.

Acne products can be expensive, so I was happy to see the Hero Mighty Patches available at Costco.

Each package contains 54 original patches for nighttime use and 27 invisible patches that can be worn during the day. These patches can extract pus and visibly shrink whiteheads.

The Hero Mighty Patches are $23 at my Costco.

If you have a busy lifestyle, the King Smith treadmill could be a good way to accomplish your workout goals at home.

This product comes fully assembled and has a USB charging port, a 250-pound weight capacity, and a brushless motor (so the walking pad runs smoothly and quietly). It's also foldable, making it easy to store in small spaces.

The King Smith walking pad is $500 at my store.
