Trader Joe’s is a “unique your neighborhood” grocery store that offers a variety of products with rich cultural traditions at affordable prices. This is a part of their mission statement
“You might expect indulgences like these to come with unbecoming prices. But at Trader Joe’s, we’re as much about value as we are about great food. In other words, we keep our costs low, cut out the middleman whenever possible and pass our savings on to you in the form of terrific everyday prices. So you can afford to be adventurous without breaking the bank.”
