There used to be a place where you could buy Stack Exchange branded gear, what happened to it?
Unfortunately, it no longer exists. The short story is that it was just too much work for the amount of sales we had.
The long story is, we have a lot of remote employees in different states. Our sales tax burden for selling tangible goods started to become an administration nightmare. We also couldn't justify the costs of either having someone at the office ship swag or paying a fulfillment house to do it for us (we were doing both). It also was complicated by the fact that a few months ago, a group of people defrauded us for a few thousand dollars in merchandise before we caught it.
We only averaged maybe $20-$50 a day in sales. Sometimes a week would go by without an order. We also felt like allowing anyone to purchase our swag made it a bit less awesome when we sent it out for free to people for being awesome on our sites.
So we closed the shop. We'll continue to make swag, and continue to gift it to people in special circumstances, but you won't be able to purchase it anymore.
I apologize to everyone who is upset by this news. We should have foreseen a lot of these problems beforehand, and we didn't, so it's my fault.
