Now and then I find myself selecting all the 150 or so active listings which have watchers, wanting to change their prices. The trick is to not try to change items which are too close to the ending time, or which have active offers on them.
What I do is select all the candidates, and try to revise them (with no changes). Then I manually remove the ones which fail, and make my changes in the remainder, and either revise or stop-and-list those.
Is there a better way to select a bunch of active listings and determine which of them cannot be revised? It seems to demand a round-trip through the API to do. Selecting and checking which can be listed is not correct, since I am not duplicating them.
