What's the difference between 売り切り and 完売?


Do both of these mean "sold out"? What is the difference, if any? And how
might these be used differently in sentences?

For example, if I were to ask a convenience store clerk if a certain
campaign/item was still in stock and I wanted to ask, "is this sold out?"
which one would I use?




売り切 **れ** and 完売 roughly mean the same thing, "sold out". We commonly see both
売り切れ and 完売 on a signboard. When asking a store clerk, you can say either
Xは売り切れですか or Xは完売ですか. The difference is not large, but 完売 sounds more
technical because it's a [Sino-Japanese
word](https://en.wikipedia.org/wiki/Sino-Japanese_vocabulary). 売り切れ is
probably more common in speech.

売り切 **り** means [something
different](http://jisho.org/word/%E5%A3%B2%E3%82%8A%E5%88%87%E3%82%8A). Its
meaning depends on the context, but the basic underlying meaning is "once
we've sold it, that's the end". For example, 売り切りの商品 means an item that won't
be restocked. 売り切りのゲーム refers to a package game as opposed to an online game
with monthly billing system. It can also refers to bargain/sale/clearance.
