TJX, Ross, and Burlington are planning to open about 300 U.S. stores combined in 2017, according to CNBC.

Why this matters: That's about the same number that Macy's, Sears, and J.C. Penney are closing this year. This is further evidence that if retailers aren't offering extreme discounts or extreme convenience, they'll keep losing business to those who do. Plus, guess which retail chains have seen climbing stock prices over the past year? (Hint: the off-price stores).
