I imagine Skin Tyte, in addition to antiseptic, ink and metal, would also have potpourri, scented candles, incense or similar, thanks to Devin' current new-agey leanings.
Global Imports is like the imported ingredients or spices aisle, with a lot of interesting and conflicting scents.
Junk in the Trunk would be musty and reek of elk and that aging thriftstore despair miasma.
CrosStitch would probably resemble a theater costume shop anywhere merch isn't displayed- lined with huge fabric bolt racks, scraps and thread tailings all over, and smell like that mildly pleasant 3-in-1 light machine oil you use on industrial sewing machines, plus something sweet and maybe formaldehyde. Like a fabric store moved into a funeral parlor.
SBP is obviously every car garage ever, including Sam smelling like WD-40, Lava soap and/or that gritty Fast Orange stuff.
D*C is totally scented with Things You Cannot Name Or Afford.
