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.

Kirkland Signature Cashew Clusters
