Amazon has now made the big move to offer Sunday deliveries to certain cities such as Philly, Cincinnati, Austin, New Orleans and Dallas. From records, it appears that most common Sunday deliveries include baby supplies like newborn apparel, books and toys. Their decision to do this will surely push them ahead in the competition between other e-commerce businesses. However, their expansion is very costly and does not look good on Wall Street. While Amazon's sales have shot up, their shares took a pounding due to negative reactions from investors in regards to their downbeat outlook and increasing expenses.
