You don't have to have an item on sale for any length of time before it can be sold at a sale price. It can go immediately on sale.
I have had the same situation where i found an item on a sale table but when i checked, it was placed there in error. The law applies to an item that is priced as on sale or has a sign that specifics a sale. The item must be sold by law at the price indicated even if in error.
A retailer has to charge you the sale price if the price that you choose in their store is on sale. They cannot hide from you the fact that the item is on sale.

The price of a single item will vary depending on the item, and half the value of two items. The amount of the item will be one because it is a single item. If there are two single items the amount will be doubled and will be worth twice the amount of a single item. In most cases if not all, a single item is worth about one third of the price of three items even if you buy one and get one free. If you get two for the price of one the single item amount will be two but the price will be one.
Most of the time you can use a coupon on a clothing item that is on sale. You may not be able to use it on a clearance item though.
You can know if something is a potential sale if people are looking at the item. The item will most likely be a sale if someone is asking questions about it, especially about the price.
