(Refiles to correct typographical error in headline) BERLIN, May 3 (Reuters) - German retail sales posted their biggest year-on-year increase in March since the start of the COVID-19 pandemic, data showed on Monday, as the relaxation of some lockdown measures boosted purchases of clothes and shoes. The Federal Statistics Office said retail sales jumped 11.0% compared to the same month a year earlier in real terms after an upwardly revised fall of 6.6% in February. The March reading overshot a Reuters forecast for a decline of 0.3% Sales of textiles, clothing, shoes and leather goods rose 27.7% compared to the same month a year earlier, while retail trade with goods sold in department stores was up 23%. Online retailers continued to benefit from shifting consumer habits with sales up 42.9% compared with a year earlier. German states started allowing shops to offer so-called appointment shopping deals, called “click and meet” in March.
