As crowds descend on the nation’s High Streets this week, following the reopening of non-essential stores, the savviest shoppers are to be found trawling charity shops and vintage emporiums for deals. Second-hand shops were braced for a flood of donations similar to the volume received following the end of the first lockdown, as millions of us have once again had plenty of time to clear out our wardrobes. Last summer Cancer Research UK saw a 31 per cent increase in donations, while Oxfam’s online sales over Christmas were up 90 per cent compared with the same period the year before.
