Google Checkout insists on displaying the COUNTY name all in capitals, no matter how I type it (in merchant profile). The Royal Mail specification, however, is that the POST TOWN should be in caps, not the county; the county, in fact, can be omitted in the address as long as a postcode is shown.

Also, Google Checkout insists on displaying my six-digit local phone number as two triplets, no matter how I type it. UK practice is to write all six digits in one block (though ISO guidelines say to divide into pairs from the right). In any case, the triplets style is wrong.
