Yeah, the speculator market on everything from cards to comics has been blowing up again recently. A mere hint of a character in one of these MCU shows can spike the price of books featuring them drastically.
I got a good laugh out of seeing the Flagsmasher origin listed for $100 "Buy it now" with an auction at $41. It's a terrible run that the MCU will turn to gold.
It looks like this show is pushing Zemo and the other villains toward The Thunderbolts.
