Yes, it’s called the 2PAC Official Store. You can browse there and buy vinyl versions of all his albums and various merch, such as posters, clothes, ornaments, and homeware. However, there are a lot of other Tupac merch options to choose from on different online stores, so I suggest not limiting yourself to the official one. The biggest benefit of the official one is that all the products have guaranteed high quality. When looking at other stores, such as Amazon, you may come across poor-quality merch options every now and then.
