Thought this was cool… someone is making customer NES Cartridges to sell along with those who bought the new LEGO NES 71374 set that comes with Mario Bros cartridge.
These are sold out right now at LEGO… and selling for around $300, plus or minus on most sales. Not terrible flip but sometimes with these if you intend to flip LEGOs you hold out longer, over time unopened box sets go for way more…
