I have long read this thread and came here last night before ordering a 537 from Walmart. Because I knew from here that if the price went down today I would be able to request the new price, which I did.
But before ordering last night I checked Sam's Club and noticed that they had the 535 priced at $218.88 in store only. But just now I checked Sam's and the 535 is now availabe online at the $218.88 price.
