I was a pretty regular user of the Go store near my commuter train home.
Lately there are numerous items at my store that have gone out of stock, some of them for a few weeks now, and telling them about it gets a shrug and a "sorry, 'corporate' controls inventory" response. Not sure what 'corporate' means here but okay.
Long story short - Go is a fun thingy but I don't think they're ready for retail. I deleted my app.
