I like to visit thrift shops.
I do too! I enjoy the low costs but also how some items can be sold at competitive prices.
I like how there is always something new and different every time you go.
They mainly sell used goods but most of the time you can find them in good condition.
Yes and there is so much to look at there.
A thrift shop is also know as a charity shop run by a charitable organization to raise money for a good cause. 
I prefer to shop at the ones that actually do go to a good cause.
All remaining income from sales are used for the stated charitable purpose after all costs are paid.
Goodwill does not work that way though.
They are funded by a massive network of retail thrift stores. They operate as nonprofits as well.
