Under quarantined, many people are passing the time by undertaking cleaning projects and getting rid of old clothes.

Donating clothing, however, has become a bit of a challenge, as many donation sites remain closed because of the coronavirus.

What to do? Well, some people are reselling their old styles for cash instead.

“Because donation centers aren’t open, it’s a really great way for them to get it out of their house and also for me to be able to keep going with my business,” said Perez. “With me offering to possibly pay for the items that they are giving me, it’s kind of a win-win for them and for me."

Perez said shes' been busy ever since posting the idea on Facebook.

“The immediate response was really overwhelming,” said Perez.

With so many clothes, she even started renting a storage unit to hold everything. Before that, "everything was in my living room,” Perez said.

ThredUP has a program through FedEx and UPS that allows people to send their recycled clothes in without leaving their home.

“We send you a prepaid cleanout bag. It holds, like, a laundry basket worth of stuff. You fill it with all the stuff you are no longer wearing and we pick it up from your house,” said Reinhart.

Oh has been picking up people’s clothes from their porches,  as a way to practice social distancing. She also gets a lot of the clothes she resells from friends and family.

“All my friends are cleaning out their closets because they're bored. So, at this point, they have bags and bags of things and they are like, ‘What do I do with it?’” said Oh.

“I would say it’s not unreasonable to look for a thousand, two thousand, maybe even three thousand dollars a month."
