I just don't understand why anyone would cancel their preorder... there is literally nothing but bad that could come from cancelling. Best case scenario, you cancel and the the Tamagotchi P's really is discontinued. You don't get a P's. Or, you cancel, and then they fix the issue and others get a P's, but you don't. Or you cancel and they get them back in stock and you still don't get the P's. Even if you decide to buy from another site, even if you keep the preorder you can still cancel it when they fix the issue/come back in stock and there has been no obligation to pay.
Besides, HLJ have said that they will set the item to Discontinued so no further orders can be made, yet preorders will not be affected. And if you cancel, you cannot reinstate or reorder your preorder. You've lost it, until they can get them back in without any preorders left to fulfil, which who knows when that will happen.
Like really I just don't understand. I'm keeping my preorder until they fix the issue. Logic would say that they cannot be discontinued already, they've been released for 5 hours. People need to calm.
