As a single person, I try not to overbuy too many goods, but I can't resist the call of Costco. I go about three times a year to stock up on my favorite staples.

Although many people venture to Costco for food, I mostly get household, health, and beauty products — like this Dove bar soap.

This package of 16 soaps sells for $16.99, which breaks down to just over $1 per bar. In other stores, a two-pack of this product can cost over $4.

Oral-B's Glide floss is my favorite. It's thin and silky, so it easily moves between my teeth.

This six-pack costs $16.99.

When I do buy food at Costco, salmon is my first choice.

The wild Alaskan salmon costs about $18 per pound, and I usually buy up to a 2-pound slab. When I get home, I cut it up into filets and freeze them.

I don't take a multivitamin, but I do take a few supplements for energy, like B-12 — though the effects vary from person to person.

I grabbed a bottle of 300 tablets on sale at Costco for $18.99, and I won't need to buy more for almost a year.

I dust my home at least once per week, and these Swiffer dusters are my favorite because they catch every spec.

You can spend over $10 for a 10-pack at some other stores, but Costco sells 28 (plus a handle) for $16.99.

I only have one cat, but the amount of fur he sheds around my home can feel like five. So I don't know what I'd do without these dry-sweeping cloths I use to clean my floors.

You can get this large box of 50 cloths for $14.09.

I've suffered from chronic migraines since I was a child, so I always keep medication on hand.

I used to take a name-brand tablet, but when I found this option at Costco for about $19, I made the switch and saved money in the process.

This bottle comes with 400 tablets, so I also won't need to buy more for a while.

Kirkland's allergy pills are a great price.Joy Loving

I experience allergies all year, not just seasonally.

So each year, I pick up a bottle of 365 Kirkland Aller-Tec tablets for about $14 to keep my allergies at bay.

Comparatively, a 30-count bottle of Zyrtec, a popular name-brand alternative, can cost over $20.

I'll often snag a three-pack of Roncadin's pizza.Joy Loving

Costco has a few different multipacks of pizza with three or four medium to large pies.

I usually pick up Kirkland's four-pack for $16.99, or a box of three Roncadin pizzas for $14.99.

Most frozen, single pizzas at other grocery stores can range between $5 to $9, so both options are solid deals.

I like the fresh scent of essential oils to hit me as soon as I walk through my door.

This pack of eight (plus one plug-in) keeps my home smelling great in-between cleanings or no matter what I'm cooking. I can choose from scents like lavender and chamomile or fresh waters.

Some stores sell packages of two AirWick essential-oil bottles for about $8, but Costco offers this nine-pack for $15.99.
