> I looked on Amazon, saw some "3rd party" sellers that said they would have it on stock various dates about 1 week in the future, and I didn't believe them.

They're planning to drop ship it when you order it. Only then will they realize it's out of stock (or they'll wait weeks for it from China).

A number of times I've had a reseller dropship from walmart.com or target.com for a few dollars of arbitrage.
