Query: my first online purchase

Hi ,Buying on line for the first time was a bit tricky but I got the book I wanted. The postage is slow and expensive but I was warned about that. Books great.The postman here crammed it into my letterbox and damaged it so I wish it had been packed better - more rigid - especially for the price.I think profits on overseas postage are a bit of a cash cow for the greedy so I will take care to avoid that if possible in future.
