To be honest, on Sonoma there really just aren't enough vendors to justify a website. I generally don't recall, which sends me across Brittannia on foot most nights, and I can count the vendor shops I've located on two hands, the stocked ones on one hand. I doubt even the stocked ones will stay that way, they never seem to. It's a shame, really.
Luna is nice for it's convenience, but a terrible price is paid. Anyone who advertises (read: drops runes) their shop just gets bought out, their wares moved to Luna to be priced higher. Who cares, right? The vendor made the sale at his desired price.
Personally, I can't stand the Luna buyouts. It goes against the "spirit" of what most non-luna vendors do, which is offer sane prices and an alternate location to that cursed city. Not only are the Luna vendors too lazy to get their own stock, they are potentially ruining the outside vendor. I know I usually don't return to empty shops, which is the illusion these buyouts creates for hard-working merchants.
A vendor I frequent because I enjoy the place sells necessities. Bags of potions, bandages, arrows... you name it. Nothing I couldn't buy or make myself, but it's a neat little adventure shop out in the boonies and I try to throw business that way when I can. Twice now I've seen Luna vendors there buying it out. I mean, come on. Seriously? You're jacking the bandages and potion sacks? Your Luna house isn't making enough profit, you have to screw this merchant out of her wares? For such a small shard, the greed knows no bounds, it seems. Best of luck with your shop, you'll need it.
Yours for judgement and persecution:
