Did you see some of their other prices... Canon PowerShot S5 IS - $185.00!! The cheapest I've found this camera for is around $300. The last time I saw a sub-$200 price was on a couple of web sites run by companies in NY that tried to up-sell you. For every purchase, you had to call a number to confirm your order. Once on the line the rep. would state that the item was in stock and do their best to sell you overpriced accessories (e.g. filters for $149.99 that can be bought for under $40 - we're talking the same brand and model of filter). If you did not want the add-ons, then all of a sudden the item was out of stock and would not be in for a few weeks.
This place may be legit, but you know the old saying: "if it looks too good to be true..." or, maybe more appropriately: "if it sounds like a duck, walks like a duck, ..."
