Click-n-Ship address quirks

[dpd1]

I'm sure anybody that uses USPS online has run into the situation where the CnS refuses to take an address, even though you know it's right. From what I've been told, there is no way to force the system to take an address, unless it jibes with the database... Which of course can be flawed. What I'm wondering, is if any of the outside services like Endicia don't have this problem?

I have had way fewer problems this way with stamps.com. Also, with the latter you can just cut and paste the entire address into the box instead of having to enter each part of the address separately, like click-and-ship had the last time I used it. There is only one screen instead of a bunch, and it allows you to do international stuff (which does have multiple screens). It is just way faster and easier than click-and-ship, even if you have to pay for it.
