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.

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.

Scallop Tufted Bath Rug

Bottom Line

Saving on random, amazing finds isn't the only reason Costco shoppers are so loyal. The retailer is known for its bulk finds and incomparable bargains. One of the top grocery savings hacks is to stock up on groceries without going over budget when shopping there.

Although it's fun to go shopping at Costco and find products that are just too good not to add to your cart, consider bringing a shopping list to make sure you get all you need without overspending on things that aren't essentials.
