Answer:
The price of the item goes up.
Step-by-step explanation:
Sellers know that people are willing to pay more to get something that is limited. It's kind of like bidding. The prices go up over a single item. So, sellers will up the price so they make more profit. It's the same vice-versa. If there are lots of an item and not a lot of demand, sellers will lower prices to try and persuade you to buy them with the low price.
