I send out ALL orders well within 24 hours of receiving them. Personally.
If you didn't get your stuff right after ordering it, the reason could be your Paypal payment was an "echeck" and didn't clear right away. Packages might travel more slowly than letters because of the size or whatever the postman had for breakfast in Wichita Falls, TX.
Anyway, people in the UK and Australia have been getting their orders in four (YES, 4!) days after ordering them. Just ask BlueHippo; he was angry that it took longer to get to him in the midwest than it did to the United-fucking-Kingdom.
Anyway, hope this allays your fears.
