“You get what you pay for when it comes to shoes.”
You're commenting on an Internet forum about fashion. Someone has asked how she can find really nice shoes for a low price. You don't think it's possible to buy nice shoes cheaply. You write this because you think that she should pay more for a nicer pair of shoes.
You get what you pay for when it comes to shoes.
"You get what you pay for" is a common English saying. It means that cheap items aren't very good; you have to spend more money to get a good item.
People use this saying a lot when they're talking about whether to buy a cheaper item or a more expensive one.
Use this phrase to express the topic or range of a statement. In the example above, the speaker wants to say that "You get what you pay for." But she only wants to say that about shoes.
Use this when you want to make a statement which only applies to one specific area:
You're a good cook in general, but you're absolutely amazing when it comes to desserts.
