cheap tyres online

I never really thought that you can buy so many things over the Internet. I mean, I always thought that online shopping was far more convenient than the regular, mundane shopping, however, after yesterday I doubt that I will EVER buy anything the regular way. Yesterday I started to surf the Net a bit. I do it quite often. Frankly speaking, I do it almost every day after work. An hour or two of surfing in the Net just to find out the latest stuff etc. I also check whether there are some good occasion to buy some stuff. Yesterday I learned about extremely cheap tyres. Those tyres were so cheap that I still do not know whether it is not a fake. I phoned them today to ask whether their cheap tyres are really new and not secondhand or something like that and they told me that they are brand new. That is why I bought those cheap tyres online and I am anxiously waiting for the outcome. I want them to come already. I mean, they were so cheap that I am wondering if there is no catch of any kind. If there is no catch, I will definitely do online shopping every single time I want to buy something. Rarely can you buy stuff that cheap the normal way. I mean, it looks like people know how to sell their stuff and that is why they aim at the Net.
