Make sure there are enough funds in the account. Amazon tends to cancel orders until all funds can be paid out of your account. Contact Amazon for full details of what you can do to help them create the order, so you can get it to ship. Amazon doesn't take any money from you until the item ships. For those that are not "fulfillment by Amazon," you'll have to wait at least 30 minutes for the item to complete the transaction - These Marketplace sellers don't see any of your order until that window is clear.
The infomercial industry is huge and is worth a staggering $250 billion as of 2015. It all started back in the late 40’s and early 50’s when major sponsors of serial television programs were soap manufacturers (i.e. Proctor & Gamble, Lever Brothers and Colgate-Palmolive), which is how “soap operas” got their name. There is some controversy although the first infomercial is thought to have been for a blender either made by VitaMix or Waring Blenders and aired in 1949 or 1950. Time limits for commercials were imposed by the Federal Communications Commission (FCC) not too long after this which halted the growth of infomercials until 1984 when those limits were removed.
