If anyone still wants to buy the toy guitar they have reduced the price to "only" *checks notes*... £247.50, I guess they overestimated demand for this limited edition product.
Yes, this product still perplexes me a lot. I think album releases should look something like this nowadays. I don't want CDs, give me something unique! They should've packed all these box sets, 1996—2007 and 2019—2018, and put it out with this guitar, complete with hi-res 24bit/192kHz audio on a USB-C drive, a bunch of bonuses and whatnot. THAT would sell like ice cream on a hot day. But the music industry is still driven by dinosaurs.
