Like Malcolm McDowell said in Star Trek: Generations, time will hunt you down and this far though my time I find myself away a lot looking after an elderly relative, so I'm not as flexible for shipping your item as I'd like to be.
This means I ship on one day of the week.
That day is dependent on where I am that week.
If you are kind enough to purchase someting from me, I'll be in touch almost immediately to tell you where I am and how soon before I go to the post office.
Communication is key, after all.
