The used to sell there, zero discount. Afaik they don't sell any sort of blemishes or "factory seconds" or anything along those lines and buying direct from SF you can expect full MSRP.
I'm not going to try to talk you out of buying surefire products, they know how to build a bullet proof light, but you can get better performance at a fraction of the price by looking elsewhere that's still 100% reliable in adverse conditions.
If your just going to check them out that's understandable but if your looking for a light might I suggest Armytek or even foursevens/Olight (separate companies but the same guy runs them both so they're products are pretty similar)
