February drug on a bit longer than usual this year, but March is finally upon us. In addition to daylight saving time, buzzer-beating college basketball shots and that day everything turns green, March represents a great time to stock up on certain essentials.

Once again, the newly redesigned FreeShipping.org offers advice on what to purchase this month as part of its comprehensive Best-Time-to-Buy Guide. Save on!

1. Frozen Foods

There's a reason to celebrate everything these days, and March is no exception. Recognized as National Frozen Food Month by the National Frozen and Refrigerated Foods Association, consumers can find deals on frozen delights including fruits, veggies and more.

2. Perfume

You can usually find great deals on your favorite scent now that the two biggest holidays for perfume purchasing are behind us. Better yet, search for your fragrance at discount retailers like TJMaxx and Ross or at warehouse stores like Sam's Club. Such stores have perfume and cologne for a fraction of department-store prices.

3. Gardening Tools

If your garden has a post-apocalyptic look to it since last season's harvest, now is the time to bring it back to the land of the living. Lucky for you, March is the best month to buy gardening supplies as home improvement stores stock up for spring planting.

4. Winter Coats and Apparel

Though spring fashion has inched its way onto department store floors since January, consumers will see the biggest overhaul this month when spring officially arrives. That means deep discounts on winter coats and other apparel while retailers make room for the new season.

5. China and Flatware

Are your plates and utensils a little worse for wear these days? Consider upgrading with last year's patterns as dish retailers gear up for wedding season. Bridezilla can concern herself with the latest in dinnerware design, and the rest of us will save big on her rejects.

6. Air Conditioners

As temperatures rise, so do prices on air-conditioning units. March is likely the last month to take advantage of off-season service pricing as well as discounted units from last year. Merchants want to clear their shelves to make room for the latest and greatest before summer strikes.

7. Luggage

If your go-to luggage is so threadbare it can barely contain your clothes, consider upgrading this month. Manufacturers release new models ahead of the busy summer travel season, making last year's models a great buy.
