Do you ever wander through the grocery store and end up spending more than you were budgeting for? Don't beat yourself up over it — supermarkets actually have several different strategies to trick customers into blowing bucks. Be on the alert and watch out for the sneaky psychology tactics these stores will try to use on you.

你有过在超市里逛来逛去，最后却发现买的比预计要多吗？对此你不用自责——事实上，超市为了诱导消费者买更多东西，有很多不同的策略。对这些超市试图用在你身上的心理学诡计，你可要保持警惕。

1. 10 For $10

1. 10元钱买10样

10 for $10 sounds like a great deal. However, you'll get the same savings even if you only buy one item, according to the New York Times. A grocery store survey recently found that people bought way more items when they see 10 for $10 deals vs. five for $5 and one for $1 sales. Even if you aren't buying 10 items, your mind will trick you into thinking that the item is such a great deal that you end up buying more of it.

10元钱买10样听起来很合算，然而，据纽约时报报道，你就算只买一样也同样能省钱。最近一项针对百货店的调查发现，当人们看到“10元买10样”、“5元买5样”、“1元买一样”时，他们会买更多东西。即使你没有买十样，但你会想既然东西这么划算，那就多买一些好了。
