Just wondering, as I have seen both of these things happening, and of course there is nothing worse about your wishlists than long desired items disappearing without a notice... ~sighs sad
I've been so frustrated by this; I give up, delete it from my wishlist & then buy something that's second best, only to find the item I originally wanted has magically reappeared. Why don't they just keep it listed as out of stock?
Our inventory is constantly changing. New products come in, old products go out of stock. Sometimes a manufacturer will pull an item if they have an issue with it.
If you see something you really want, get it while you can! The best you can do is submit a support ticket to ask if it's permanently OOS or if we have an ETA on the item, and don't forget to set alerts!
