I think these are all wondrous items that have prerequisites that would prevent them from being bought. Most of them are too pricey to be bought in Orussus anyway, but I've marked those that could be bought with an exclamation mark or two. The weapons and armors are in the thread linked above (with one error; the sword of planes shouldn't be on the list, since plane shift is 5th level for clerics).
