I am writting to you as soon as I saw your email.
I hope it is not too late.
Of course I think it is a great idea.
Moreover I think it is the best idea because it is the most comfortable way of buying things.
I almost buy everything by internet except food which I use to buy it at the supermarket.
I have taken this way as my usual way of buying things.
About the payment I would say to you to be careful and aware of the danger of getting into a web page which could not be save at all.
Apart from this in the majority of the webs pages you can pay through the post.
Do not worry If you have to return something back the usually do their best to fix the situation.
