Right now, the tech driving the Amazon Go store works well if there are only a few people inside and if they're moving slowly according to WSJ's sources. However, this isn't an accurate representation of a real-world environment where customers will expect to stop in, grab what they're after quickly and leave immediately. It seems that the company has delayed opening the lone Go location to the public until it can remedy the issues.

When it was first announced, Amazon said you would be able to stop by in "early 2017" and the Go information page on its site still lists the same estimate. We reached out to Amazon for a comment on the matter and we'll update this post when we hear back.
