easy fundraisers

I am really struggling for money at the moment, so need to REALLY limit the amount that i spend.
What do you think about buying SOME clothes for me and my kids from charity shops?Do you think its skanky, or ok?
The same goes for own brand food from supermarkets?

I want to get good quality second hand clothes. How do I figure out where to go i.e. what area the charity shops are in?

Charity shopping in London is becoming quite expensive. I’m looking for charity shops/boot sales that still offer great bargains, with view to buying stock for a vintage store.

Travelling to the outskirts of London is possible.

Any serious tip offs greatly appreciated. Thanks.
