Memorial Day weekend has turned into a legitimate major retail event over the last decade. It's not just mattresses and appliances anymore -- though those two categories are still where you'll find the best deals. Here's what's actually worth buying and what to skip.

Mattresses: The Biggest Sale of the Year

No other retail event does more for the mattress industry than Memorial Day. Casper, Purple, Saatva, Tempur-Pedic, Nectar, and essentially every mattress brand runs their biggest promotions of the year around Memorial Day weekend. We're talking 20-30% off for direct-to-consumer brands, with free accessories (pillows, sheets, mattress protectors) often bundled in as well.

Physical mattress retailers -- Mattress Firm, Sleep Number, Ashley -- run aggressive promotions too, often with financing deals. If you've been sleeping on a bad mattress and waiting for a reason to pull the trigger, Memorial Day weekend is the reason. This is the single best time of year to buy a mattress, and by a meaningful margin over the next-best time (Labor Day).

Appliances: Second Biggest After Black Friday

Major appliances (refrigerators, dishwashers, ranges, washing machines) see their second-best discounts of the year at Memorial Day, after the Black Friday window. Home Depot and Lowe's both run substantial appliance events, and Samsung, LG, and Whirlpool push promotions through their own sites as well.

This is a particularly good time to buy appliances if you're doing a kitchen or laundry renovation and don't want to wait until fall. Expect 15-25% off on mid-range models, with floor model and scratch-and-dent deals going deeper.

Outdoor Furniture and Grills

Outdoor furniture is in peak season right now, which means prices are not at their absolute lowest -- but Memorial Day promotions do bring real discounts from Wayfair, Home Depot, and Lowe's on patio sets, grills, and outdoor accessories. If you need outdoor furniture for the summer, buying at Memorial Day sale prices is much better than buying at full price in April. Waiting until fall clearance (September-October) gets you deeper discounts but you've lost the season.

Grills specifically see strong promotions. Weber, Traeger, and Nexgrill run Memorial Day deals consistently. The new-model rollout for grills tends to happen in spring, so the "previous year" models that are often perfectly fine see clearance pricing.

Home Improvement and Tools

Lowe's and Home Depot both use Memorial Day as a major promotional event for tools, hardware, and home improvement categories. Milwaukee, DeWalt, and Ryobi tool sets often see their best non-Black-Friday pricing. If you're planning a project and need to stock up on tools, the Memorial Day window is worth watching.

What's NOT on Sale

Summer clothing: Just arrived on the floor at full price. The summer collection launch is not the clearance event. Clearance on summer clothing happens in July-August to make room for fall inventory.
Electronics: For the most part, Memorial Day electronics deals are thin. Wait for Prime Day in July for the meaningful tech discounts.
Groceries: Some food items run promotions around the BBQ holiday weekend (hot dogs, chips, beer), but these are shallow promotional cuts, not the kind of discounts worth optimizing around.

Best Retailers for Memorial Day

Lowe's and Home Depot both commit heavily to Memorial Day with promotions across appliances, tools, and outdoor categories. Wayfair runs a major Memorial Day home sale that covers furniture, bedding, and outdoor items. Mattress-specific retailers (Casper, Saatva, Purple) have their biggest events of the year around this weekend. If you're buying in any of these categories, it's worth checking all of them and comparing.
