Not to play Devil's advocate too hard, but I find it a bit baffling when people complain about getting banned. Target (and other stores) have pretty open policies about their rights to ban suspected resellers. I don't wish ill on anyone, but a lot of folks in the "game" are pretty selfish, and they don't understand not only do their exploitative policies hurt themselves, they hurt everyone in the long run by having stores changing policies that make things harder on everyone. I've witnessed it in real time over the years.
If folks used a bit more restraint and weren't as obvious (And let's be honest, we're all resellers here) - maybe they'd avoid the banhammer. Maybe don't order 10k of stuff during one sale. Normal customers don't do that. If you aren't willing to face the consequences of a speeding ticket, don't speed.
Spread out your orders, be patient, use different sources = don't get banned.
People get bent out of shape when someone undercuts them by a penny, but no one seems to bat an eye when a couple shortsighted folks make huge orders that cause massive fallout throughout the industry. It's very narrow sighted.

On an unrelated note, I think it's interesting Target is kind of doing their clearance this way. Markdown the prices online, ship stuff from stores. Saves them the time and hassle of stickering/restickering/moving stock in stores. It's a pretty smart move really. And stuff is more likely to move at 50% when the whole country is the customer base, as opposed to stuff hanging out til 70% in stores. And it avoid them dealing with the closeout stores.
