Hands up those who find that dealing with time zones from one side of the world to the other can be SO frustrating! Online marketing and selling obviously goes on 24 hours per day but unless you have a staff who can man phones and computers for that period, then there can be a significant delay in getting back to potential buyers.
You would hope that such buyers would realise that you aren’t ignoring them and will get back to them as soon as possible, but I would hate to think that sales are lost due to people wanting an immediate response.
Not much more to add, but just needed to get that off my chest! Rant over… lol
