Here’s a quick flip potential. Midtown has their Exclusive Stranger Things Mattina Signed Variant for only $10. That was the same price as the unsigned copy.
These are selling for double the retail price currently with a few in the $30+ range and most listings for $40 or more.
I actually bought my regular copy while in NYC, should have known since he was signing books at their booth they’d have the signed edition a few weeks later for the same price.
