When stores have great sales or discounts, they sometimes limit how much of something each customer is allowed to buy. When they do this, they write something like this on their signs and advertisements:
Limit 3 per customer
If you describe the limit in a sentence, you say it like this:
There's a limit of 3 per customer.
