每当去到大型商超脚步就挪不动了，琳琅满目的商品诱惑力实在是太大了。控制不知买买买的想法怎么办？知道了以下这下方法，就可以避免你在逛商超时大手大脚了。

Here are the mistakes you’re making when you shop for groceries, and how to fix them:

以下都是我们在买食杂品时常犯的错误，此外还有一些如何避免它们的建议：

Coming in without a list
进超市不列单子

Meal prep is key here. If you plan your meals for the week ahead of time, you’ll walk in with a plan and be less likely to stray from your list by compulsively grabbing pricey snacks or random ingredients that will sit in the back of your pantry unused.
关键是要给自己下一周定个食谱。这样你走进超市时，心里已经有了计划，也就不会一时兴起买一些昂贵的零食，或是随便拿些买回家根本不会做的食材。

Going to the store hungry
饿着肚子逛超市

This is probably a no-brainer, but always eat a meal before going to the supermarket. Nothing good comes out of a shopping trip when you’re starving. Lifehacker suggests chewing mint gum while you shop so you’re less likely to fall victim to the store’s scent marketing tactics (yes, that actually exists).

这个道理是显然而见的——逛超市前一定要吃饭。如果你饿着肚子逛超市，你的消费肯定是不理性的。Lifehacker网站建议，你在超市购物时可以嚼一块薄荷口香糖，这样你就不会掉进商家“气味战术”的陷阱里。

Being too lazy to use coupons
懒得用优惠券

We’re not suggesting you make coupon-clipping a competitive sport like those extreme couponers, but there are several insider tips you can learn from them. The Krazy Coupon Lady advises buying your groceries at multiple stores to find the best discount, and to remember that certain chains take competitor coupons.
我们不是建议你像那些走极端的“优惠券狂魔”一样，把大把的时间用来剪优惠券，但这东西上面的确是有窍门的。“疯狂优惠券大妈”（The Krazy Coupon Lady）网站建议道，你可以多去几家商超，看哪家折扣力度最大，而且你要记住，有些超市还接受竞争对手的优惠券。

Shopping on the weekend or in the morning
周末或早晨去超市

Believe it or not, there are better days and times to shop. Most people do their grocery shopping on a weekend so they can prep ahead of time, but mid-week is when products with short shelf lives like meat and dairy go on sale. Plus, there are more discounts as the day wears on and stores need to get rid of perishables. Your best bet is to shop on a Wednesday night, says Lifehacker.
你相信吗，购物能不能省钱，也是分时段的。多数人都是周末买食杂品的，然而周内才是像肉类和乳类这种上架周期较短的商品打折的时候。另外，一般来说，越接近晚上，越是超市需要处理掉易变质食品的时候。所以Lifehacker网站指出，去超市采购最省钱的时间是周三的晚上。

Ignoring sale cycles
不了解销售周期

ales at supermarkets aren’t random; they run in 12-week cycles. Stop being shocked at the price of meat when you walk in the door by learning the ebb and flow of sale cycles. You can see an example of a month-to-month sale calendar from Krazy Coupon Lady here. Another tip is always buy produce that’s in season: it’s cheaper and usually fresher.
超市并不是心血来潮了才打折，而是有周期的，这个周期一般是12个星期。如果你窥得销售周期之道，趁打折季进店大采购，肉价会便宜得吓你一跳。你在Krazy Coupon Lady网站就能看到一个“销售周期日历”的例子。另一个小窍门是尽量买应季食品，因为它不仅更便宜，也更新鲜。
   
Here’s a little-known tip: cheaper items are usually stocked on the bottom shelves, whereas your expensive items will be stocked at eye-level. Why? Unless you’re in the know, the average consumer will unknowingly spend more just by shopping by line-of-sight.
最后还有个小窍门：便宜商品一般都堆在最下面那层货架上，而比较贵的商品才摆在与你的视线等高的货架上。为啥呢？因为大多数消费者会不自觉地把注意力放在视线轻易可及的范围里，这样商家就可以多赚些钱了。
