While there are some post-holiday sales and special discounts, there are plenty of things you are better off waiting to buy. Here are four items that shoppers should be skipping in January.

Tax software

Sometimes the early bird doesn't get the worm. April 15 is quickly approaching, but getting a head start on your taxes may not pay off. You may want to wait until February to buy tax software from TurboTax or H&R Block. "Last year, we were seeing sales in January on tax software, but what we're predicting is that the sales are going to be stronger in February this year," said Trae Bodge, smart shopping expert of TraeBodge.com.

Luggage

While hotels and travel expenses will be cheaper this month, you will have to wait a bit longer to find a new carry-on bag on sale. Since fewer people are traveling, retailers have fewer incentives to mark down their luggage prices. If you want a new suitcase for your spring beach getaway or big summer adventure, it's best to wait a couple of months. At that point, stores should be clearing out inventory from last year to make space for new products. They will also offer discounts to entice spring breakers in March.

Clothing items

Don't be surprised to see retailers debuting their spring styles this month. "You'll start to see some spring things in there and things for vacations and resorts," said Michelle Madhok, online shopping expert and founder of deals site SheFinds.com. "If you can, I would not buy that now, because it'll get marked down as the season goes on." But whether you should buy winter apparel in January or purchase it later depends on your personal preference. Bodge said you are better off waiting until February for the best deals.

Mattresses

Typically, you will find the best sales on mattresses around Presidents' Day, which falls on Feb. 18 this year. Retailers take advantage of the three-day weekend's extra shopping day, and new inventory appears in March. Don't worry if you are not quite ready to shell out any money for a mattress in February. You can also find good mattress deals on three-day holiday weekends around Memorial Day and Labor Day.
