Amazon's "One-Click" ordering has made it so easy to make an online purchase that even a toddler could do it. In fact, a toddler has done it -- buying a $400 couch her mother knew nothing about. San Diego resident Isabella McNeil says she was baffled when she recently received an email from Amazon, notifying her that her new couch had been shipped. "I thought, 'Did I buy a couch in my sleep?'," she says. Then she recalled letting her 2-year-old daughter Rayna play with her phone a few days earlier and figured out what had happened. Unfortunately, it was too late to stop the $400 piece of furniture from arriving. "Lesson learned," says McNeil, who's now attempting to sell the couch on OfferUp. "Now I know it's really dangerous and I need to make sure the Amazon app is closed before my daughter takes the phone. It's just so easy."
