Also, although I have no direct contact with the capper, let me just add that its entirely possible that the sticker on the bottom of the bottle simply fell off, I know this might seem far fetched, but as a consumer, I have seen about a half dozen or so bottles from a couple of companies that I wont name, where I have seen the exact same thing happen.
And if it helps you at all, epi was pretty much sold out all over the place, including NP, a new shipment went out, NP got a new supply, and you got a new bottle. I just checked a new bottle and the exp sticker on the bottom reads 07/11. I can offer my apologies to you if this caused you any grief, but like M16 wrote, it will be good for a long, long while, so unless you planned on freezing it for six-seven years(which Im not recommending by the way) you should be good to go.
