I am a physician, so the situation is different, but I always bring my computer along on vacation to check labs, refills and messages from my staff every day while I am on vacation. I think a person who is selling items that could be gifts should anticipate that a buyer purchasing in October to November is buying a Christmas gift, and so an order arriving after Christmas would be unacceptable. Also, my brother is a tax attorney, and he wouldn't think of taking a vacation between now and mid-April. So, in the same way, if I had a business where I made handicrafts that would be Christmas gifts, I wouldn't take a vacation right before Christmas, because that would be my peak season.
