Depends on the store, some will give you the goggles for that price, some will send you an email that says you can either keep them and get charged the full price or cancel and they refund your money. I know backcountry depending on the item (a while ago they had the dakine double ski bag normal around 200) listed with amazon for $50 but amazon fed up when they took Backcountrys info and copied the wrong product code and price but everything else was legit, Backcountry sent out a bunch of boot bags instead of the ski bag. They offered a refund for the bag they sent out and free comped all shipping charges so that might be what your looking at.
On the other hand i know backcountry put up a pair of road bike bibs on their bike site for 0.07 a bunch of people got them for that price, for everyone who ordered before it was caught BC gave away 1 pair of bibs for free, if you bought 10 you got 1 pair completely free. so you never know what amazon and the other site will do. Good luck though.
