Tough question to answer for me. I pass on the vast majority of LEs (and all CC LEs), even from my favorite brands like Tatuaje, Illusione, and Liga privada. Instead, I will buy or trade for like 2-5 cigars after the fact from BOTLs.
But when I do get in on it, I typically buy a box. Usually I "win" in that the one I gamble on buying a full box of is awesome (Boris, Tat Tubos, NHC Tat, Flying Pig). But there are always some that I "loose" out on--like the Tat T110--by finding out when it's too late that it's frickin' great.
Even so, I'm not planning to change my style and buy more. It's fun to try Pete's test blends that didn't make the cut, etc., but I have a lot of cigars and don't smoke enough to justify box purchases often.
