Bham, do you know what the expiration date is on the USA juice that is on sale?
I know I'm a day and a half late to this party but since no one answered...
I threw a couple bottles of Outlaw Apple in my last order (2-3 weeks ago) to hold me over until I find a suitable replacement, and I can tell you that the expiration date on those bottles is October 2012. I can't say whether they're all like that but I'd say its probable. It would certainly explain the large sales price.
Is it worth it? I guess it depends on how you look at it. Like milk, some people won't touch a product after the expiration date, others see it as a "sell by" date. If I remember correctly, I think Mdir said he'd vape juice up to 6 months after expiration as long as the taste was still there. Ultimately if that's good enough for him, then a 10/2012 expiration is probably good until at least the end of the Mayan long-count calendar.
Milk is another story though. I won't drink milk if its within a couple days of expiration. My roommate on the other hand will drink it a week after and not even flinch. Wait, why am I talking about milk again?
