It's a multi-billion dollar a year industry.
Thrift stores provide everything from clothes to furniture to electronics and household items at bargain prices.
Marjorie Boudreaux with Goodwill said it's one of the fastest growing names in the thrift store industry.
The non-profit company opened its 13th store in South Texas on Thursday morning.
"You can find brand name items for less than $5 and you can outfit yourself for under $20," Boudreaux said.
The new store at 702 Dixieland Road in Harlingen features spacious shopping.
"We found there's a lot of need for thrift shopping here in the Rio Grande Valley, and so we want to be able to provide that to the shopper," Boudreaux said.
Thrift store shopping has become more popular among teens and college students, who may not necessarily have the cash to shop at full-price retail stores.
Boudreaux said donating and shopping at thrift stores is good for the environment.
"It really is socially responsible to be smart with money, environmentally conscious, and begin 'upcycling'," Boudreaux said.
