The display case was $80 new. Those ebay listings... it's a thought. Edited: I see what you mean... some have sold recently at high prices. Hmm... these display cases are rather huge 14x18, heavy and glass. Costly to ship, difficult to package and prone to breakage. Still, it's an option. Thank you for suggesting.
Taking the advice of mom2rtk, I just went ahead and sent a complaint email to
shopDisney guest services basically saying that I'd been suckered into purchasing a limited edition series of 10 that is still incomplete after a year and a half. I requested a refund. (I used much nicer language, obviously). We'll see if I get any response at all.
P.S. I bought 2 of the display cases and 2 each of the 8 pins that were released. Intended as gifts for my daughters. Of course, I never expected I'd be gifting in 2022 or later! LOL
