A high-quality, healthy snack is optimal during December's maelstrom of activity. As a solo household, you'll benefit from these 30 individually wrapped bars made with real nuts.

Price: $29.99

With the high spending in December, keeping the house cooler can save money. This oversized wearable blanket keeps you toasty while you read or watch TV without constantly adjusting the thermostat.

Shoppers love the water-repellent fabric and the hood, which helped reviewer Stacia stay "warm and dry at my grandson's football game."

If you're attending a New Year's party later this month, this fully lined bodice sequin dress can dazzle. Since it's a "wear-once-a-year" item, you don't want to break the bank.

Price: $24.59

Laundry pods are best for those who live alone because they don't have to measure soap while washing their Christmas finery. With 104 Ultra Oxi pods on hand, you'll have shiny, fresh-smelling clothes for months.

A half-pack, or 57 Tide pods, costs $19.99 at Target.

Price: $49.99

While this gift set would arrive too late for Christmas, consider it a practical present for your household of one if you're a pasta lover. It comes with crisps, pasta, sauce, dessert squares, orzo, all nestled inside a functional colander.

Price: $36.99

Staying toasty overnight during chilly December is possible without turning up the thermostat. This lightweight comforter gives you warmth without the heavy weight or frequent dry cleaning.

Even though you're a solo eater, if you go through peanut butter regularly, this 48-ounce twin pack is perfect for your pantry. It also lasts for a long time.

Price: $15.99

Dry hands are a bane of December. You may think a three-piece hand cream set is overkill, but you'll be able to keep one cream by the sink, one by the bed, and one in your purse for less than $20.

Besides, each 1.4-ounce cream in the set addresses a different common skin problem, so you'll be tackling them concurrently.

Price: $18.49

If you enjoy a salty, crunchy snack, but don't want to overeat, try these 42 1.75-ounce bags of Chex Mix. They're perfect for an afternoon indulgence, movie night, or keeping a spare in the car for December errands.

Your Costco membership means you won't pay over $24 for the same amount at Walmart.

Price: $17.99

Sponges that soften in warm water and firm up in cold water make cleaning easier, which is a lifesaver during December. Eight sponges in one pack last a long time in a single-person household, no matter how busy the kitchen.

They are a favorite with shoppers. "They last a long time and don't get a gross smell," explains reviewer Stella K., who highly recommends them.

Price: $18.99

Snacking on nuts at Christmas time is the perfect way to enjoy the season's bounty. This variety pack includes 24 no-shell packs of regular, sea salt and vinegar, and chili in 0.75-ounce individual portions.

They offer better value than Target's variety pack of nine assorted bags for $8.29.

Price: $21.99

Watching your diet during calorie-heavy December? Individually wrapped protein snacks are the best choice. The 12 Chomps in this pack can help you stay full between errands.

Reviewer Michael B. feels these meaty treats "further his membership value" as "yet another Costco advantage."

Price: $27.99

To enjoy the season, consider this plug-in ceramic warmer shaped like a Christmas tree or gingerbread house, along with three scented wax packs in festive fragrances like vanilla pine or cinnamon apples.

It's a functional piece of Christmas decor that is more cost-effective than buying multiple candles. "This is a perfect addition to my Christmas decor," writes reviewer Fran.

Living alone doesn't mean giving up warehouse savings; it just means shopping smarter. The best Costco December deals for solo households reduce waste and simplify routines without requiring bulk consumption.

Another smart way to save money at Costco is to watch for the quiet price drops on seasonal comfort items like candles and apparel after the holiday rush, when you get the best value without competing crowds.
