As is so often the case, the deals tend to all come at the same time. Within moments of posting the FramesDirect thing, I got notification of another 30%-off sale at Goggles4U. Goggles4U is one of my original retailers from my very first pair of simultaneous orders.
They have a massive selection, and seem to have added even more name-brand closeouts at prices ranging from excellent to less-than-excellent-but-also-less-than-everyone-else.
Check them out and use code "Deal" to get 30%-off for the next 72 or so hours.
