Yeah, also the fact that most venues take a cut of merch sales really dampens the idea that buying merch directly from artists is the best way to put money in their pocket.
I even recall going to a show many years ago where the lead singer refused to sell his t-shirts at the venue and implored us all to meet him outside at their tour van for direct sales. I don't think he got invited back to perform there!
Never heard about venues taking a cut off the merch - that’s fucked up… They already take (in almost all cases) 100% from drinks and bar sales. In my experience the ticket sales and merch go completely to the artist. Anything else I would consider a rip-off
