They asked me to FE (BTC fluctuations were too much for him or some such thing) before they ship even though they already marked it as shipped. I decided I'd oblige. When I checked today I discovered that they cancelled it and gave no reason as to why.
They pulled something like that on me as well. Told me they'd ship it just as soon as I FE... twice. Even gave me some crazy sob story about how I was an asshole for moving the auto finalize date a few days off while he goes through all sorts of shit to do his thing. Interestingly enough, this came just after I noted that his feedback looked sorta funky.
