Advice for saving money / getting best experience at Texas Ren Fest?

The main thing I had in mind was savings on the entrance fee. I've heard in the past Costco has offered Texas Ren Fest bundle at a good deal. I don't live that close to my nearest Costco, but did check their website: the only tickets that came up were for various sports games, but maybe it's too early? I also don't know how the tickets work, if you can purchase them online and get them as an email/PDF or if they only have physical stubs. From what I have read online it seems like it might be the latter and not appear online? Does anyone know if Costco still sells Texas Ren Fest bundle tix and if I can get them online? I am assuming they are only available in Costcos in/near Houston (or maybe broader Texas), not nationally.

Also, if you have any other tips for saving money / getting the most out of Texas Ren Fest let me know!
