Hello, I haven't done that yet, because we are right between book 1 and 2, but I will, when we finally come to Katapesh. This is how I would do it: I would look through the magical item section and decide what would be usefull, interesting, funny or needed in the hands of my players. Then I would roll a few times extra on the tables, change stuff a bit so that it feels good and than, depending on how much item I have, I would distribute them to a number different shops so that no singel shop feels too overcrowded.
And another thing would be, to flesh the shopkeepers out. Not with stats, but with quirks and mannerisms. This way every shop would have its special and unique feeling to it. And if the PCs like the wares of one shop and buy there some stuff, next time the shopkeeper could have a special item just for them, that he set aside for his best customers.
I remember, in a very old campaign, my GM described the stuff that a shop had to offer, and there was one special weapon that he got into great detail, but that was way out of our reach at that level. And it was always there, smiling at me, when we visited town again and I always knew that I would get it someday :> It was a really great feeling when I finaly, after many adventures and levels, had the founds to buy it. Such big signature commodities in a shop should have there own storys. It would be fun, if the shopkeeper tells you a different story, every time you come back to his shop, so you never know which one is the truth ... or if all are just made up ... or if every story has a little kernel of the real story in it? Thats the oriental spirit :D
