I love books. I love reading books. I can't buy them fast enough and I will go through a few books in a week. And of course, I love buying books.
These can be great to buy online in shops or auctions. In the auctions, you can get a lot of bargains if you buy a few at a time from the same seller. Most sellers are happy to combine postage for more than one item.
The only thing to remember is to carefully read the item description and ask all the questions you need.
Things to ask:
Are there any markings, writing or missing pages in the book?
If not, you should be alright. Read the item description carefully because there is nothing worse than asking a question when it has already been spelled out in the description page.
