well, I'll throw the wrench in.
One of the reasons I buy from Mountain Oaks Vapors, and a few others, is
precisely because they are vapor-sealed at the facilility.
Other companies I buy from have that plastic seal wrap around the cap which extends up over the cap. Just like a bottle of aspirin or something.
In this day and age, when I receive my juice, I want to know only one entity had "access" to the inside of my bottle---- and that is the actual mixer who put my juice in the bottle.
Plenty of turnover in this biz and I have no way of knowing that some disgruntled employee in shipping tampered with my juice, any more than YOU have no way of knowing if one of your customers who wants to return a product does, right?
That is why IMHO, I'm not paying $0.35 a ml and I'm paying over $0.60 a ml or $1.00+ a ml for MY vendor juice.
Long gone are the days of "kitchen sink" juice mixers, w/some high school student's bubble jet printer for labels, etc. (and I got all those from "premium vendors" when I started out until I learned better)
Count ME as a customer who wants a professionally packaged product.
While it may be true, as you say, that you cannot ascertain if the customer tampered with the juice, you also can't ascertain that anybody between the mixer (and that could even be a shipping department) or somebody else along the line til the juice reaches a customer) also hasn't been tampered with, can you?
So not sure what is the difference. If it's not sealed it is not sealed, and
you should be tossing out all juice that comes back from ANY customer, regardless of what their reason is for returning it...........or take down your refund policy as it is presently worded. Their reason for returning it isn't going to make difference if they decide to return it, right? I mean, you have still lost that juice and lost that purchase $$.
JMHO
