the act of shopping at retail stores with the sole purpose of finding items that have been greatly discounted by being put on clearance sale. Some buyers set clearly defined rules for clearancing, such as only buying items that are at least 50% - 75% off the original retail price. While not always the case, it's not uncommon for someone clearancing to buy items they don't really need, but will purchase because it is "such a great deal".
"You won't believe the great deal I found while clearancing today - a $30 purse for only $7.50!"
"I know I don't have a fish, but I just couldn't pass up the .25 cent fish food I found while clearancing today."
"My eBay store is filled with clothes I've picked while clearancing."
