For what it's worth? I've identified the box being that of Siege: War For Cybertron Omega Supreme.
This is a Titan Class figure, basically the BIG one of an entire series for a YEAR which kids have as the number one thing on their letters to Santa, with a bunch of playability with a base mode that can link up to other mini-bases, the figure itself is probably the size of a one year old, and the cost would easily be north of $150 MSRP
minimum. Chris likely paid much more from a specialty website that actually had it in stock since most brick and mortar stores do not carry Titans due to the shelf space they take up.
This figure is also fairly recent, being only a 2019 release. Since he had to have gone out of his way to get Omega, it's certain that he's been buying the
other giant-as-fuck figures like Typricon, Metroplex, and "Ark" (the giant spaceship that crash lands in the original series and becomes the Autobot headquarters on Earth? Yeah that's also a robot now). Chris being irresponsible with money is nothing new, however.
