That would be bad policy on their part. I was shopping at microcenter, saw a Logitech MX-1000 performance wireless mouse with a $39.99 pricetag, rang up at the register as being $99.99, they sold it to me at the $39.99 price because it was their mistake.
Amazon are pretty harsh on this. I bought 10x £120 motherboards for £12 and they refunded them all. The only time you'll get them is if you get prime ordered and they went into processing within 30 minutes of ordering.
