Is there a way to look up items per shop? I'm looking through the Freyalise Trading Co. shop for the holiday and I have no idea whether or not I have an item before I buy it. I know I can search the item directory for it but by the time I look it up, the item's gone. I know other shops that have their own currency (or places like zombie den) have it to where in the shop it shows, but this one doesn't. The regular item directory is great and I use it fairly often but to be able to just go somewhere and say "I want to see EVERYTHING that Sole Train sells" and just get a list would be amazing. Not to buy, to avoid item sniping, but just to see it, like how the item directory works.

I'm also confused on how things listed under "Retired" work but that's not as important.

You'll need subetalodge.us for that. They have all items lists that can be sorted by restock location, price, rarity, etc. Item directory by itself doesn't do that much.
