Implement savings techniques

You know where and when to buy, but how else can you save? Here are NerdWallet’s best school shopping tips:

- Find the best price.Compare prices from multiple retailers by conducting a Google search or using a tool like ShopSavvy. In most cases, you’ll need proof of a competitor’s price if you want to request a price match.
- Do the math.Calculate the price per unit to make sure you’re getting the best deal, even when items are sold in different amounts. Paying $6 for a pack of 20 pens (30 cents per pen), for instance, is better than paying $4 for a four-pack ($1 per pen).
- Know the return policy.Checkthe store’s return policy before you make major purchases, such aslaptops and tablets. It’s usually listed on the website. Look forthe length of the return window and any items thatare final sale ornon-returnable.
- Buy online, pick up in store. Many retailers givetheir shoppers incentives to buy online and pick up their items in store. Some offer free shipping to your local store — includingKohl’s and Wal-Mart—while others discount your order or, likeMacy’s, providea coupon for next time.
- Shop with a credit card.Usingcredit cards for back-to-school shopping can boost your savings, thanks to promotional deals and cash-back offers. Some give bonus points forpurchases at department stores or wholesale clubs.
