I totally agree with what you are saying. Its very frustrating when that happens.

As a seller, I have active ebay phone alerts on my phone. So if I am out,  I will still get my messages and I will respond accordingly.

It costs time and money to list, so if you don't  respond to your buyers, 1) its a waste  of money, 2) time, 3) unprofessional 4) Buyers don't forget good customer service , BUT THEY DONT FORGET BADDDDDDDDDDDD CUSTOMER SERVICE.

I love good communication between bidder and buyer and if that doesn't happen,  I get really peeved off. It is very rude for a person not to respond to any emails when it only takes a few minutes of your time.
