Especially limited editions. Those are pretty much the only things where I've ever bought multiples.
Okay, well I've never had something cancelled except for OOS situations like Majora's Mask console.
Fire Emblem Fates special editions, Wticher: Wild Hunt CEs, Juggernog Editions, amiibos when they were new, Pokemon Go, Tales of Berseria CE, and on and on. It's not random when a person has never had a cancellation. Maybe they treat Elite and Elite Plus members orders differently? I put in 3 orders for 3 Zelda BotW SEs the other day too. I've never ordered more than three of something, because that is the GCU limit.
