I've worked at Costco for 20 years. Here are 7 of the best things I'm seeing on shelves right now.

The Kirkland Signature Nike SB Dunk Lows created a frenzy online.

One of the most unexpected — and talked about — items Costco recently released was the Kirkland Signature Nike SB Dunk Lows.

These sneakers, which are a collaboration between Costco and Nike, are only available at select warehouse locations and are pretty difficult to find.

My store didn't have any, so I drove 90 miles to a location in San Francisco. Although it's unclear if more will be released, I feel lucky to have snagged a pair.

Silicone freezer trays make meal prep easy.

This set of five Miu silicone freezer trays caught my eye as a way to make meal prep and portion control easy.

The trays, which come with lids for easy stacking, can be used to freeze soups, broths, smoothies, or even leftovers.

The RXBar protein energy bites look delicious.

The RXBar strawberry peanut-butter bites — made with real ingredients like peanut butter, egg whites, apples, strawberries, and dates — are a great on-the-go snack.

Each serving is loaded with 8 grams of protein and 200 calories.

Hefty Shrink-pak bags make it easy to store bulky items.

The Hefty 12-piece Shrink-pak bags are a great way to compactly store and organize bulky comforters, pillows, towels, or clothes.

Each box includes 11 bags in various sizes and a hand pump to remove the air.

Macaron pops make the perfect gift for Valentine's Day.

If you're looking for a unique way to express your love this Valentine's Day, Costco has you covered.

The macaron pops by Macarooz are beautifully decorated to look like roses and are made with real red-velvet versions of the classic treat.

Get ready for spring with Disney's adorable train set.

It may be cold outside, but I'm already looking for ways to decorate for the change of season. Disney's delightful spring-themed train set caught my eye, and features classic characters like Mickey, Minnie, Donald, Goofy, and Pluto.

The train has dainty lights that function on a timer, and even plays music.

The Amylu breakfast bites are a great way to spice up morning meals.

Amylu chicken-sausage breakfast bites are a great way to keep meals tasty and interesting. Each serving is packed with 14 grams of protein and 150 calories.

These can be found in Costco's freezer section.
