The weather is warming and the unofficial start of summer is just weeks away. Retail deals change with the season, so it pays to know what kinds of offers are blooming this spring. If you’re looking to score some great value, here are some of the best things to buy in May:

Mattresses

May is one of the best times of year to buy a mattress. A new mattress is a great way to freshen your home, ensure you’ll get good rest during the busy days of summer, and prepare for that influx of summer guests you’re expecting. Stores are trying to clear out old inventory in preparation for the new stuff they want to sell during the big Memorial Day sale, so if you’re willing to buy last year’s model of mattress, you can get a great discount — before the end-of-month sales that everyone else is waiting for!

Refrigerators

Many retailers discount large appliances in May — again, in preparation for Memorial Day sales. Because many refrigerator manufacturers unveil their new models in summer, look for stores to discount last year’s styles as they try to make room for new stock.

Jewelry

You may be tempted to give Mom a new piece of bling for Mother’s Day, but hold off. Jewelry prices that go up during peak buying times, like the weeks before Mother’s Day, will drop significantly after the big day has passed — and stores find themselves with an excess of inventory. Wait a week after the buying frenzy and you could find exactly what you’re looking for at a fraction of what it was selling for in early May.

New furnace

People rarely spend proactively on big-ticket items like a new furnace, but if you know yours is on its last leg, this is the time to replace it before it dies altogether. Furnace makers and installers see sales drop in spring and summer, meaning May could be a perfect time to replace your old, inefficient furnace and score a great deal on a newer, more energy-efficient model.

Snowblower

The same principle of diminished demand applies to winter items like snow blowers. While everyone else is pricing lawn mowers and grills, May can be a good time to prepare for next winter by scoring a deal on one of the last snow blowers your local hardware store has in stock.

Carpet

Sales of home-improvement items like carpet are going to peak in summer, so get in ahead of the rush. While everyone else is thinking of graduations and planning summer vacations, carpet sellers experience a lull in late May. Buy between the middle and end of the month, and you can probably score a good deal on carpet and installation, too.

May is that magical month after winter and before things get busy with graduations, weddings and summer vacations. Take advantage of the breathing room to score some deals on items that will make your life easier throughout the rest of the year.
