I will make an unusual statement: in some countries, it is easier to give.
First, a backgrounder.
In the US, we held some garage sales. It is easy. You just gather the things you do not use out of the closet (or the garage), put a price to it, set it up at your garage (or yard, for a yard sale) announce it over the internet or advertise in some local newspaper (for free), show up on the day with some loose change, preferably psyched up to deal with penny pinchers (who want your memorabilia for a song) and wait. At the end of the day, you will have earned some cash, freed a part of your garage (or closet), and found homes for the stuff you would not miss anyway.
