I made a purchase with a vendor on AB for some China White. Have ordered the same product from this vendor in the past and it has always showed up in 3/4 days. It is going on 7 business days, which isn't that long, just unusual. It is my first time ever checking the "use vendors pgp" box. Is it possible he did not decrypt it properly and sent to a wrong address? I know there is another week of waiting before I worry but I am just curious if that is possible or not?
No. The message will either decrypt or it won't. It's impossible for it to decrypt to something else other than what you sent.
