Was looking to put this in the tips section but its disappeared???
My Mum just called up to tell me about this,so posted it on here,more details on main Oxfam site.Shame it wasn't on food you could get £5 off as there isn't really much else I buy in there.
How it works :-
When you bring a bag of donated clothes containing at least one item of M&S clothing to any of Oxfams 750 high street shops, youll get a voucher for £5 off your next purchase of £35 or more of clothing, homeware or beauty products in M&S. Offer starts on 28 January 2008 and vouchers are valid during the calendar month in which they are received.
