Like Christmas Cake的意思|示意

像圣诞蛋糕 Fortunately there is hope for consumers in the form of a market in mooncake derivatives. Mooncake coupons are often given out by companies to employees, to exchange for the real thing. Or they can sell them to others at a discount to the mooncakes' market price. The trading season is short and frenetic: the coupons are nearly worthless once the holiday is over. Like Christmas cake, mooncakes are rarely consumed out of season.
