Don't bring the kids.不要带着孩子逛街，因为父母总会为孩子买些不适用的东西。

You wouldn't believe (or maybe you parents would) how much more junk parents buy for their kids that is completely impulsive. Working as a checker at a grocery store, I quickly learned that most of the time kids were with their parents, the parents would buy something else within 10 feet of the check stand.

Bring exact cash.不要带太多的现金，这样就不会毫无节制的花钱。

I like to use my debit card because I am able to track every penny better, but holding and letting go of cash is much tougher for me personally. So, if I am going through a tough time budgeting properly, I will bring the allotted amount of cash to the place of business and only allow that to be used.

Ignore salesman.不要太在意推销员的话，要知道他们的目的只是让你：掏钱！

If you are at a department store and someone asks if you need help, try to ignore their push as much as possible. Sure, if you know nothing about laptops, get their advice, but even then I suggest doing your research pre-shop. Salesman could care less what you want. It's all about what their quota or commission is. Ignore them.

If a celebrity is pushing it, pull back.不要被明星或名人代言的产品迷惑了双眼，选择适合你自己的才是好的。

In Michael Pollan's new book Food Rules, he discusses the general notion that if some type of celebrity or popular figure is pushing a food product, than it probably isn't healthy. How often do you see Paris Hilton promoting apples or Lindsay Lohan wearing affordable clothes. There's a tendency to be highly influenced by the promotion of products. So, if it isn't being promoted, you will probably buy the cheaper and more appropriately priced item.
