Square Enix is hilariously bad at merchandising. I've mentioned this in surveys they've sent out over the past few years because I like collecting little doodads and supporting the game. Aside from job pins and magnets, most of the affordable merchandise is basically Japan only. They come out with lower cost items for claw machines and gachapon, which aren't entirely inaccessible but are a pain to get if you don't know how to find it. They have such hugely popular IPs that they could be earning money out the wazoo (see the MTG collab doing gangbusters) and despite owning a toy production company (Taito) they just... don't.

It's a problem with the company as a whole and one they've left mostly unaddressed for years.
