Strongly support. Maybe bundle the crayons, pencils, etc as well? Like, uncommon bundle of Grayscale Art Supplies, rare bundle of Glow In The Dark Art Supplies, and so on.

I'll also mention one more thing from the discussion thread: some way to stock up on crafting rares that doesn't involve shop stalking for hours because you need several rares for one thing. Like quests that reliably reward those rares.
(Especially relevant for tailoring rares, since there are several patterns that require multiples of the same rare item)
(Especially Satin. Please, give me a way to stock up on Satin)

Support for bundles and a materials tab for Kei- Not sure about Jay being separated for food vs. non-food (unless you mean adding the kitchen and misc items to recipes???) since A) don't know if there will actually be enough non-foods to properly fill it and B) Not sure I want/if it's even possible to have 2 extra tabs for Jay, since she already has recipes.

Some possible Kei bundles while on my mind- in addition to facial features some possibilities-
Bangs selections (divided by rarity)
Eye selections (again divided by rarity probably)
maybe group facial hair together? Though there may not be enough for selections to help a whole lot if divided by rarity

Possible Andre bundles, just based on quick look at what is stocked atm
Common neckwear (bowtie, ribbed scarf, silk tie, etc.)
umbrellas (open and closed, blepper as well if want to group common and uncommon)
Stockings (gosh grouping some of the stockings together would be SO HELPFUL for some quests)

I support! I really like the idea of bundling things in those shops! I’m not technically a newbie anymore but I would still find it useful now, and even back when I was a newbie!

I also really like the idea of having materials in Kei’s shop! Possibly just the ones for the patterns sold in his shop?

I would like to see the option to purchase Half Dozen bundles from Jay's shop. It does not help with the item diversity issue but does help with the "getting the items we need" issue.
