Trash bags aren't glamorous, but they're something every household needs, especially during December when cooking, cleaning, and hosting all ramp up.

Winter is the perfect time for warm drinks, and this big box of green tea bags offers comfort without the cost of buying a similar name-brand pack like Twinings for nearly $20. Kirkland's blend is smooth, lightly herbal, and ideal for morning routines. The quantity means you're set for the entire season.

It's also a gentle caffeine option compared to coffee, which many older adults appreciate.

Price: $16.99

Warm feet are a winter essential, and this wool-blend pack delivers comfort without the itchiness of traditional wool. They're soft, insulating, and perfect for daily wear or relaxing at home.

Given that many premium wool socks like Carhartt's can cost nearly $30 per pack, this multi-pack is an excellent value. They also make great stocking stuffers.

Price: $11.99

These dryer sheets help keep winter laundry smelling fresh and feeling soft, especially with heavier fabrics like sweaters, fleece, and bedding. A single box lasts a long time and costs less than name-brand alternatives like Bounce. They're also great for reducing static, which is something that always spikes during dry winter months.

Costco's under-$20 Kirkland items prove that budget-friendly shopping doesn't have to mean sacrificing quality, especially during a season when household costs tend to climb. And if you really want to save more on everyday essentials, be sure to keep up with Costco's ads and monthly deals.

Keeping an eye on monthly warehouse deals, stacking savings with cash-back cards, and only buying what you truly use can help you stay ahead of rising prices without giving up the products that make life more comfortable.
