Charity-shopping is alive and well in Dublin, and Oxfam Ireland’s city-centre stores are among the best for a guilt-free rummage. Racks of donated clothing, books, records and bric-a-brac raise funds to fight global poverty, so every purchase does some good. The stock changes daily, so regulars pop in often. Bring a few euro in change and a keen eye, and consider donating any unwanted items while you are travelling to keep the cycle going.
