One of the nice things about brick-and-mortar stores is that I can grab an item, pay for it, and then have it. With Amazon, I can't grab an item, and paying for a product only means that I have spent money. Now Amazon can't find the product. They claim it was shipped, but never paid for shipment, and have no shipping info. According to Amazon's tracking, the shipment was lost in transit. They "sent" a replacement, supposedly certified overnight. I always thought there was a receipt that you got for certified mail. Amazon says no. Not for business certified. Amazon "sent" a second replacement, then cancelled the order, because they can't find it to send. I requested a refund. Now, Amazon says I must wait for all 3 to be resolved. They want USPS to take care of all 3. USPS refuses, saying Amazon must provide info.
