Found some of these (4 boxes) in a B&M (in California). The prices include the high California tax but the good thing about it is that they have 5+ years of age on them.
There is one box of #4 (6x50 double corona), and 3 boxes of #6's (5x49 robusto). The shpo owner says they all have 5+ years of age and it could be 6+, he wasn't sure, but definately 5+.
I have pricing and he is offering 15% off for a 2 box purchase. Email me for info if interested.
