When you list an item it automatically registers where you are and lists the item as being in that location. Other users can then search for stuff they want and thw results are ordered in terms of what is closest to their location.
Most of the time people collect the stuff directly from you which makes it great for selling larger items like furniture. This means you get paid in cash.
Occasionally someone will ask if you would post an item (which I do if it's something small like clothes) and they pay you via PayPal.
It is really quick to list items!
I have shifted loads of stuff on it some getting it last autumn.
Best advantage: because people are collecting from your house there's almost no effort involved on your part and being paid cash means you can sell stuff for £1 and get £1 rather than ending up with 10p once platforms have taken their cut.
Worst disadvantage: because your phone registers where you are when you list an item you have to be at home when you list and can't do it on the go or while bored at a friend's house.
I would completely recommend this app. It's so easy to use and has lots of users which means lots of potential customers!
Enjoy!
