What is A markdown greater than 99 but less than 100?

A markdown greater than 99 but less than 100 refers to a discount on an item that reduces its price to between 99% and 100% of its original price. For example, if an item originally priced at $100 has a markdown of $99.99, it is effectively being sold for $0.01. This situation implies a very minimal reduction, effectively making the item nearly free while still technically being sold at a price.
