Shopping pro tip: This month's best deals

April brings not just warmer weather and sunnier days, but also excellent shopping opportunities. With Easter happening on April 20, retailers will offer significant discounts on seasonal items at the end of the month, while also preparing for graduations, weddings, and spring cleaning season.

Here are some of the best deals to watch out for:

  • Cookware sets on sale for graduation and wedding season
  • Winter clearance items like coats and sweaters at end-of-season prices
  • Spring cleaning supplies with potential BOGO offers at stores like Target
  • Air conditioners before peak summer demand drives prices higher
  • Lawn care equipment as homeowners prepare for the growing season
  • Post-Easter candy and ham at deeply discounted prices once the holiday has passed
  • For groceries, consider seasonal produce like asparagus, broccoli, and spinach, which will be at their freshest and most affordable.

Remember that retailers are always thinking a season ahead. They're already preparing to get rid of spring merchandise while you're just getting ready to enjoy it. This makes April a great time to find budget-boosting deals of all kinds.

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 some of our favorite tips for reducing food expenses that we personally put to use:

  • Plan your meals around what's already in your pantry, then create a shopping list to prevent impulse purchases.
  • Buy store brands instead of name brands whenever possible.
  • Always make sure to compare unit prices, not just sticker prices.
  • Stock up on staples when on sale, but don’t ever buy just because something comes in bulk.
  • Shop the marked-down section for near-expiration bargains
  • 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 to handle every week, the savings can really add up. Double check in case your store also offers perks like gas rewards or any other discounts you might be able to take advantage of outside the grocery store.
