These guys (telemarketers) pretend to be a charity, but in fact are a big business making profits from your used clothing and items.  Everyone involved along the line from the person calling you, to the driver, to the store-front (Value Village) selling your used items makes money.  Say your old jeans sell for $15, only $0.25 goes to charity.  Give to a true charity like the SALVATION ARMY - they only have volunteers and don't inflate prices for the needy.  Value Village is a for-profit-organization from the USA.  The main owners are Tom Ellison, son of the founder Bill Ellison, and Freeman Spogli & Co. a private equity company.
