一、优惠券模板：对优惠券规则进行设置，主要包含：优惠规则、有效期和余量控制。
1.优惠规则需要对以下几个维度进行设置：
（1）类型。如zui常见的是满减券、立减券，另外有折扣券、兑换券等
（2）优惠金额。如慢200减20，优惠金额就是20元。
（3）适用商品。如全场通用券、限定类目或品pai的优惠券、指定商品的优惠券、仅抵运费的运费券。
2. 有效期：
优惠券的有效期，主要有两种模式：
（1）固定时间，例如：10月1日00:00~10月7日23:59的国庆大促券。何时发放或领取，用户收到的券的有效时间即为固定。此类券具有分批发放，活动性质的特点。
（2）领取后x天有效，主要是日常活动的券，例如：注册就送7天有效的券。特点是用户领取的时间点不同，有效期也动态变化。
3.余量控制：
优惠券数量的控制，配合活动预算，对优惠券数量进行限制，设置如：一共1000张。
Nowadays, more and more middle-aged people are suffering from insomnia, as life for the middle-aged is stressful indeed. For one thing, as they are the backbones of their companies, they have plenty of things to do at work. And they usually have to work overtime. For another, they have to take great responsibilities at home, for their aged parents need to be supported and their little children need to be brought up. That's why they don't have enough time to have a good rest.
