Olay Advanced Moisture Renewal Blend Body Wash

Price: $12.49 (on sale from $16.99)

Olay is a tried and true classic, but the price is rising just like everything else on the shelves. Snag this pack from Costco, which features three 23.6 fluid-ounce bottles of body wash that work to nourish and cleanse your skin.

For comparison, the Moisture Renewal Blend from BJ's will cost you $16.99. The closest equivalent at Target is the Ultra Moisture body wash, and it costs $6.99 for a 22-ounce bottle.

Downy Fabric Rinse Odor Remover

Price: $16.42 (on sale from $20.42)

Some odors seem to sink into the very fabric of clothes, resisting regular detergent. The Downy Fabric Rinse replaces liquid fabric softener and boosts regular detergent to remove stubborn smells and residues.

Costco's coupon book gets you $4 off the cool cotton scent. That's an unbeatable deal, given you'll pay more for it elsewhere.

Charmin Ultra Strong Bath Tissue

Price: $27.49 (on sale from $33.99)

If you're frustrated that toilet paper prices never really came back down after the pandemic, you're not alone.

Charmin has become especially expensive, but if you need a popular brand-name tissue, this coupon for $6.50 off brings it down to less than a dollar per roll (it's a 30-count pack).

Grocery stores like Kroger charge $41.99 for 24 rolls, so it's best for your wallet to stock up when Costco has them marked down.

Swiffer Sweep + Mop Deluxe Sweeping Kit

Price: $29.99 (on sale from $34.99)

Swiffer changed the clean floor game, offering a quick and easy solution that saves so much time over traditional mopping — but it comes at a price.

Luckily, Costco's starter kit includes the mop along with 30 refills, half dry and half wet cloths, with a $4 coupon. A standard starter kit from Kroger is regularly priced at $21.49 and only includes five dry and three wet cloths.

Shopping pro tip: This month's best deals

August is here, and with it comes the final stretch of summer. It’s a great time to soak up the season and scoop up hot deals before they fade. Look for savings on:

  • Travel and getaway must-haves
  • Back-to-school basics
  • Clearance swimwear and warm-weather styles
  • For grocery savings, grab peak-season produce, like tomatoes, cucumbers, melons, and berries

As retailers shift their focus to fall, August is the last chance to snag summer essentials at unbeatable prices. Shop smart now before the season (and the savings) slip away.

Febreze Air Mist Variety Pack

Price: $17.99 (on sale from $19.99)

The pricing on Febreze Air Mist can fluctuate wildly, based on scent and whether it's seasonal. But right now at Costco, use a $2-off coupon to grab two mist-spray bottles of Downy Infusions Calm and two mist-spray bottles of Linen & Sky.

Cascade Platinum Plus Dishwasher Detergent ActionPacs

Courtesy of Costco Cascade dishwasher pacs

Price: $23.99 (on sale from $28.99)

If you've ever gotten off-brand dishwasher detergent, then you know it just doesn't get your dishes quite as clean. The ActionPacs are more expensive than liquid detergent, but it's worth never having to soak or scrub dishes again.

Costco's packaging includes 82 ActionPacs, $5 off with the coupon. Places like Walgreens sell a smaller 52-count for $23.99.

Nature Made Multivitamin for Her + Omega Gummies

Price: $15.78 (on sale from $19.28)

If you hate swallowing a big ol' multivitamin every morning, you'll be glad to know the Nature Made chewable gummies specially formulated for women are discounted in this round of coupons.

Buying directly from Nature Made costs $17.79 for 80 gummies, but Costco offers 180 gummies for about $2 less.

Kleenex Ultra Soft Facial Tissue

Courtesy of Costco Kleenex tissues

Price: $19.99 (on sale from $24.99)

Back-to-school season is here. That means you'll want to stock up on this 12-pack of 3-ply tissues, with 85 tissues per box. With Costco's newest coupon, you'll get $5 off this household staple, and they're also allergist-approved and hypoallergenic.

Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more.

Whether or not you’re a new homeowner, a home warranty from Choice Home Warranty could pick up the slack where insurance falls short and protect you against surprise expenses. If a covered system in your home breaks, you can call their hotline 24/7 to get it repaired.

For a limited time, you can get your first month free with a Single Payment home warranty plan.

Quick tips: How to save on your grocery bill

Grocery shopping doesn't have to break the bank when you use the right strategies. Here are three quick tips for reducing food expenses:

  • Buy store brands instead of name brands whenever possible.
  • Always make sure to compare unit prices, not just sticker prices.
  • Join your store's loyalty program so you don’t miss out on member discounts.

Even though something like choosing coupons in your grocery store app can feel like an annoying task, the savings can really add up.

Gillette ProGlide Plus Razor Cartridges

Price: $39.99 (on sale from $49.99)

Gillette ProGlide Plus is popular with both men and women for a close, smooth shave that's hard to match — but the refill packs are so expensive that they're often behind lock and key.

With a $10-off coupon, Costco offers a 16-count refill pack for less than a 12-count pack from Target.

Crest Complete + Scope Advanced Active Foam Toothpaste

Courtesy of Costco Crest Complete toothpaste

Price: $11.99 (on sale from $15.99)

Toothpaste is one of those things you're always going to need, so you might as well use Costco's $4-off coupon and stash it away in a cupboard. A single tube of Crest Complete costs $6.29 from CVS, but Costco offers a 5-pack for less than two tubes from the pharmacy retailer.

Tide Pods with Downy Laundry Detergent Pods

Courtesy of Costco Tide Pods

Price: $27.09 (on sale from $32.49)

Many shoppers enjoy the convenience of Tide Pods, which eliminates the need for messy measuring of liquid for every load of laundry. But the cost can add up quickly.

Spending roughly the same amount at Target on Tide Pods only gets shoppers 63 pods, whereas Costco offers 104 in the April fresh scent.

Gillette Ultimate Protection Antiperspirant

Courtesy of Costco Gillette deodorant

Price: $14.99 (on sale from $18.99)

We all use deodorant daily, so why not get it for $4 off at Costco? The Gillette 6-in-1 Antiperspirant comes with five 3.8-ounce deodorants that offer 72 hours of protection against sweat.

For reference, at BJ's, you'll pay $18.49 for the same product.
