I've been quite lucky so far and all the people I've sold to, and had some delays in shipping, have been quite understanding about it. I don't do the "sympathy excuses" but I do try explain that I'm a work-at-home dad of a three yr old, who lives outside the city, and has no vehicle. This isn't meant to make people feel sorry for me, just to convey exactly why it may be difficult for me to get out to do shipping very quickly. I realize that this is often going to create shipping problems for me. It means I end up taking cabs a lot, which is costly, so I tend to wait until I have a batch of things to go at once.
