“购物券”怎么说

看没看过女人穿高跟鞋赛跑？也算一世界奇闻吧！上周六，俄罗斯圣彼得堡有100名“高跟鞋”选手进行了激烈的短跑比赛，参赛选手所穿高跟鞋的鞋跟不得低于9厘米，比赛的奖品是一张价值5万卢布（约合2000美元）的购物券。

Women compete in a high-heel sprint¹ in St.Petersburg July 21, 2007. Some 100 women took part in the race wearing high-heeled shoes with a required minimum height of 9 centimetres (3.5 inches) to compete for a shopping voucher² worth 50,000 roubles (about $2,000).

由图片说明可知，“购物券”相应的英文表达为“shopping voucher”。

“Voucher”在此指“代替现金的票券”，如：a gift voucher（礼券）。
