    If you want to learn why everything is usually cheaper, and what items are the best deals at your local or chain dollar or discount store, store employees have a lot of useful information. They tend to know what shoppers want — even before shoppers know themselves.

Everyone buys unnecessary things

Whether you shop at a chain dollar store such as Dollar Tree, Family Dollar or your local 99 cents store, not everything that’s on sale is necessarily worth purchasing. Bryan Waring, a former Dollar Tree employee, says that you’re not alone in buying more than necessary from these stores. “It seems basic, but everyone falls for this trap,” he says. “You go into a store where everything is cheap, and you walk out with things you don't need.” He suggests going into a store — yes, even the dollar store — with a checklist of things you truly need.

Everything is cheaper after the holiday season

Patricia, a seasonal worker at a Dollar Tree, says that the post-Christmas season means even more deals on everything from decorations to sweets. “After Christmas, all the gift wrap paper went to 50 cents, and all Christmas items were half price,” she says. “Even candy bars are 89 cents versus $ 1.”

Products are less expensive because of their size

In order for dollar stores to keep their prices low, product sizes are usually smaller than normal, according to Cheapism. Dollar stores area t the only ones guilty of this trick. Cheapism also reports Walmart is guilty of doing the same thing to attract customers.
