We use C&S occasionally when we need to use a parcel to send something out.

Really the only problem we see is buyer induced. Well I think the registration process.

They very often put their town/suburb name on line #3.

And their nearest capital city in the CITY field.

This causes a mismatch between the postcode and city and the to address fails to validate.

So we have to shuffle around the address so it all matches up.

Not sure if doing this would invalidate paypal protection since then it does not match identically with the paypal data.

Must be something to do with the registration process where the rules of address entry are not too strict.
