Do sold out Loungefly bags come back?

I got interested in the Minnie Mouse mini backpack in blue by Loungefly at the park and didn’t buy it and, of course, I see now that it’s sold out at the Disney store (what with Black Friday and Xmas season and all…). Do these tend to come back in stock or should I buy it from Ebay, where I see many that are reasonably priced? I hate to do that though b/c I wonder about condition and authenticity. I’ve never bought anything by Loungefly so any advice would be appreciated. It’s not something I would have expected to want but when I saw so many of them being worn in the parks I got attached to the idea of wearing one there someday myself. :slight_smile:
