nicxy,
So you think I should go for the one with diamond? But I don't like it coz it's much thicker than the other one, so it's a bit uncomfortable... =(
As for your photo size, your BS will definitely make you pay more to change. They'll tell you 'Sorry, that's the standard size included in package and if you want a bigger photo, you got to top up." that kind of shit.
It's up to you to decide if you want to give in and top up or make a fuss, though I'm not sure if they'll give in even if you make a fuss. And if you make a fuss, their services after that may not be as good anymore.
That's the risk we all have to take at some point or another. It's like all the businesses relating to wedding want to 'eat' us up. Even if it's only 1 minor slipup, we'll end up having to pay more.
