I would vote it depends on the emergency. You can see when the last time that member logged into BYC but messages go to emails too. Still if a person does not have the time to log into BYC, its possible that they had a real true emergency come up and its all they can do to take care of immediate pressing concerns.
One example might be the birth of a new baby. If its the first the dad might even be living at the hospital, especially if it happened to be a premie. There there is the opposite, a seemingly healthy person gets the notice of a week or less to live because of a giant tumor or whatever.
Paypal gives you 30 days I think to file a claim. So even if you don't end up with eggs you can get your money back.
She did finally respond that she is in the hospital and said she would have someone gather and ship eggs either Saturday or Tuesday. I told her that I wanted to cancel the order since It will miss the window on the other eggs that arrived today and I don't want a third hatch date. It has shown her checking in here several times before she responds to me, but I'm not accusing her of anything if she has a real emergency going on. I was already thinking I had over purchased for my current coop space so I am not upset about it! I am hoping she will refund the money at this point!
