The "shop now for the holidays" chorus grows louder amid supply-chain bottlenecks

If it feels like some retailers are pushing holiday shopping before you've even considered a Halloween costume, that's because they are.

Amazon on Monday announced what it called "Black Friday-worthy" deals and a hub to help consumers plan for holiday gift-giving and events. It follows Target and Walmart in urging consumers to buy early while gift-worthy goods are still available. 

Worldwide supply chain bottlenecks and shipping delays mean the closer to the December holidays the calendar gets, the less likely some store shelves may be filled with what consumers want most. Experts don't expect the jams to ease until early 2022, long after gifts are opened and the books are closed on retail's traditionally busiest time.
