I've used Fapppy many times in the past with no issue, so I'd been hesitant to jump the gun and write this, but after 3 weeks and no responses from him, I have to assume he is scamming US customers.
Here's what has led me to this conclusion: I placed an order from him on AB and paid for express shipping to the US. Historically, this option has never taken more than 5 days to reach me. After 10 days, of nothing, I messaged him asking to check tracking, but never received a response. I've sent 3 additional messages to this, and he has ignored all of those as well. I can see he's been logging in though, so I know he's blatantly ignoring messages.
Reading other feedback/reviews, this seems to be his new standard operating procedure. You pay for tracking to the USA, and despite his profile saying he'll check it for you, he ignores you and never replies.
This in and of itself wouldn't necessarily warrant me calling him a scammer. However this is why I am convinced he is scamming US customers. I have two separate AB accounts. One to ship to myself in the USA, one to ship to myself in Canada. A week after placing the USA order in question, I placed another on my alternate account for Canada.
This second order to Canada was also taking longer than normal, so I messaged him on that account as well to ask him to track it. Sure enough, he responded to that one saying it should be there in a couple of days, and my order arrived a couple of days later (pretty sure he never sent it to begin with). I then asked him about my other order, and communication ceased.
So be warned friends. Fapppy used to be a pretty good vendor, but he I believe he has started to scam his customers (particularly in the USA). Save your funds and go elsewhere.
EDIT:
Definitely scamming. Don't use this fucker. He won't reply to any messages, even with Trappy involved and messaging him.
Have you not noticed the shit ton of seaized packages come from Canada sent to the USA via xpress post?
It's affected multiple vendors bars/pills and guys like goodfellas and karmasydicate.
