I just received from Costco too, actually. I had some misgivings about the stealth of the order, but I'll give the package this: if it had ripped open on a machine and the contents had fallen out, it would have gotten re-bagged and sent on its way (which is my standard definition of "stealth.") I really don't think it's appropriate to say more than that, but suffice it to say it meets the criteria for one or two commonly-believed red flags.Please take this statement in context: I gave the order a 5/5 rating, and Costco was open to changing the shipping method in the future if I choose to order again. So I'm not saying it was a bad order or anything. But the fact remains that it does meet commonly believed criteria for one or two red flags (whether those really *are* postal red flags or not I don't have the expertise to comment on).The product has impressed me so far, I'll say that much. I'm finding that it's awfully difficult to get a feel for meth without vaping some of it (I've very recently given up vaping), so take it with a grain of salt, but so far I'd say it's very potent. Pretty nice all around -- I'm unexpectedly pleased with it at this point into the sack.Update on the product: I'm still impressed with its potency, but I'm getting a fucking vicious headache. Now sometimes I get headaches just from the amount of meth I take and I'm not talking about a normal headache... this is fucking vicious and my head is killing me. I hate cut... I really, really hate cut... but again, potency is still impressive.
