Trader Joe's, most times referred to as the Embassy of California, is a store that is different from a lot of supermarkets, stores and shops. It hold no sales, no loyalty program, no self checking, no coupon, no advertising, and virtually nothing that makes it have a hedge.
Trader Joe's is a grocery store that sells groceries needed by shoppers on a daily bases but what makes it different is its low lost for its products. The store is designed to look like the grocery store Disney land which would always catch the eye of customers. Unlike other stores where you see different labels and brands on its goods, goods in trader Joe's carry the Trader joe's tag but surprisingly, the store do not have any factory or place where food items are prepared but rather the company goes to high quality brands and request that the company brand its product with Trader Joe's.
From this agreement, Trader Joe's have good products in its name but funny enough, it start to look like the companies never struck a deal as the deal remains like one secret never to be exposed. Although a few store have their brands and branded goods like Whole Foods, but Trader Joe's goods are seen more as a Brand with Power than a good with trademarks.
Trader Joe's still make shoppers feel the old time of shopping with little or no technological advancement in their stores. Purchasing from the manufacturers directly allows it to sell at a cheaper price compared to other stores. Although not all its products are exclusive, but its goods are still customers' choice based on price.
