Mister Bijou last bought a passport nine years ago: the UK price was about 18 pounds sterling. Since when. . .
Apparently, new passports now cost 66 pounds. From October 2007, be prepared to pay 72 pounds sterling -- when passport is issued in the UK. (That last detail is important.) At the current rate of exchange, that post-October price is HK$1,112.
Oh, wait. Buying a passport in the UK is cheap. Here are current prices in June 2007 for UK passports issued in Hong Kong:
32 page adult passport (16 and over): HK$1,905There's nothing up there yet on the Brit Consul Hong Kong website, but no doubt those Hong Kong numbers will go up in October, too.
48 page adult jumbo passport: HK$2,305
