Hi Labelo!I'm assuming you're talking about Holy Grails that are no longer in production?
I'm basically like you, I have a window with tabs always open that I check morning and afternoon. I have ebay alerts/poshmark alerts set for certain keywords, too. I do occasionally make ISO posts here on purseforum, and on poshmark, and once it did help me get a scarf I had been looking for!
I'm sure I miss out on things occasionally. I figure that part of the fun of a grail is the search; I expect it could take a lot of time for some of them to pop up.
What is an ISO post?
merci!
