The customer that leaves your store unhappy because she didn't find a product in the right color or in the right size is not just any customer. It is a customer who has already seen your marketing, already taken the time to visit your store and has already found a product that she likes.

All of your effort from paying the rent every month to spending on advertising and making your store look attractive lead up to this one moment: when the customer is ready to pick a product and buy it…Stocking the wrong colors is like striking out with the bases loaded.
