There are plenty of web hosts out there that have extremely cheap prices. If you are trying to get really the cheapest of the cheapest, go take a look at
http://www.webhostingtalk.com/. The number of individuals trying to make a buck out of running their own web hosting service there is mind blowing. Be aware, however, that these people are usually not fully experienced on the technical side of web hosting and are typically mostly one-man efforts (as they cannot pay the bills of other employees in the company) so expect support to be sparse compared to more established hosts such as Namecheap. I have used Namecheap for web hosting before and they are great, but their services truly do come at a premium in price. Also remember your website data is probably not truly secure anywhere.
that forum no cheap, i wait here for people who can offer me cheap.
What are you talking about? Did you even check out that forum? There are offers going for as low as $1 a year. If you are looking for something cheaper than that, then I have some bad news for you. Also, cheap is going to mean that the service is probably going to be subliminally oversold and it's going to hurt the performance of your website significantly. Regardless, just make sure you are looking in the right section. You can find shared hosting at this link:
http://www.webhostingtalk.com/forumdisplay.php?f=4. The $1/year offer is around the top, although I would not trust it myself, but given that you really are looking for the cheapest I doubt anything is going to be beating that. You should reconsider your budget, honestly.
