It could just be a clueless/lazy employee. First person I talked to at mine (also Bay Area) said they "didn't" know, which is code for "I don't feel like checking".
Trucks usually come to large retail stores at like 4AM, so I doubt they would just show up "tonight".
99.9 ‰ they are in the back and you just had an uninformed employee. You can't look up the newest amiibo by name on their devices, only by dpci and dpci On the register.
When I wen't there in person the other day, I talked to an electronics person who had one of those mobile inventory checker devices on em and checked for me they had 28 Rosalina's for Sunday with a limit of one per person. I was really happy that she was there and actually checked for me.
But you guys are most likely right, the person I talked to by phone tonight is probably just some uninformed employee or just didn't want to check their inventory.
