In order to secure your purchase please reply, enclosing full payment, by 13.00 hours on 1 February 2008’.Nikolai replied to the letter and sent full payment for the painting, but his reply did not reach ZAO Picture until 3 February 2008. Peter’s response was to send a remittance of 450.000 roubles, with a letter stating that he was prepared to purchase the painting but as a valued customer expected a discount of 10%. Svetlana did not reply, but the general director of ZAO Picture was certain that as an enthusiastic art collector she would wish to accept the offer and sent her a painting with an invoice for 500.000 roubles.Required:

宋某到某商店购买了一双男式皮鞋，回家后发现皮鞋存在一定的质量问题，于是回到商店要求退货。商店营业员以店堂告示明确规定商品售出只能调换不能退货为由拒绝了宋某的要求，而宋某则称并未看到此店堂告示。对此分析正确的是：

A．宋某有权要求退货，因为宋某并未看到店堂告示

B．宋某有权要求退货，因为经营者的店堂告示的内容依法应当无效

C．宋某无权要求退货，因为经营者已用店堂告示的形式明示了不得退货，自然成为双方买卖合同中的一部分

D．宋某无权要求退货，因为商品只是存在质量问题，经营者并未实施欺诈
