If you want to support the channel please check out my buddy's eBay shop (the-sling-king). He is selling a mix of his stuff and mine. If you mention "Nick Vending" in the notes to seller I will get a % on the sale of his items too. That way instead of you having to buy a rubbish t-shirt or sticker with some dumb logo on it (not naming any other channels in particular...) you will actually get something cool and / or useful.
