Anyone know why the Unreal Engine T-Shirt is out of stock?

I came across http:// this on the Epic Games Store. I thought it looked pretty cool, but it has been out out of stock for quite a while. Anyone have an idea why?

They need more business cat!

Ohh ****. I didn’t know they had this stuff. Please get more stock so I can buy myself a present. Totally getting a UE Mug and T-Shirt.
