I purchased an iPad Air through Target.com. Was sent two separate confirmation emails about the order being successfully processed. Was told the shipment would arrive no later than 12/5/2013. By 12/11/2013, still hadn't received it. Called them, and was told by a supervisor the order had been lost, could not be fulfilled and my only option was to be refunded. In 7-10 business days. Nice. So, I spent over $500 for an item intended as a Christmas gift, waited longer than advised to get it, was only told it wouldn't be happening after _I_ called _them_, and the supervisor didn't even offer to look further into the matter.
Also, I called UPS and they said Target.com had only sent them my billing information - not the actual order. So, I was lied to as well.
Really fantastic experience. Never again.
