I am very seasoned consumer on Amazon and have just experienced a few watch outs.
Pay very close attention to small details especially when you need a product in a short time frame. Primarily, when the product is not coming from an Amazon fulfillment center.
In the last 2 weeks I had 2 orders bite me. One was coming direct from China and the other from India.
The China order was simply a pair of mini USB power cords, great price, 2 for $5.49. The deal was so great I missed the details, ordered at 8:00 PM, by 11:00 PM I was notified that the product was already shipped. Blown away, however, it was really shipped the next business day as it was coming from China. And it was sent regular mail. Goty the product 3 weeks later. So my haste cost me as I had ordered for a friend who required the product right away.
The order from India, also took 3 weeks, but this was goofy, maybe culture or whatever, they shipped the product registered mail. What a royal pain. I have product shipped to my condo in Florida and my neighbour puts the product away for me awaiting our return. UPS and FedEx are great, they know our place always leave it where required. But registered mail, it became a nightmare.
Hope my short comings help you in the future.
