Still think this is the best solution.

Just set up a single ward, with an NPC to talk to and search for items, then you just summon the Retainer you want to buy from to you. Just like when you summon your own retainer, noone needs to see the summoned retainer besides you.

Wish more people would go to this thread and post, wondering if it's just too hard too understand, but the CURRENT market wards system, even with they link the wards and spread out the population will be a pain in the ass for the devs for years, and it will not last.
