But Netfirms too not support Paypal. I don't know other firm which serves this service below $5. I know name.com only wihch is the cheapest registar which support Paypal. their fee is $5.99.
great domains with PayPal you can find at namecheap. don't know what's the cost of a .info but i think you can buy them pretty cheap.
Well .com's are difficult to get for that budget, you may get .IN though, or maybe buy 3 .INFO from the links in my signature. Cheers GS
Below $5 is difficult. But you can try mydomain.com by using coupon code " htmli.info " (Without " "), which will given you 15% OFF. Some registrar charge higher for domain renewal fee, so check the price before you buy.
If you are looking for .info domain then you can register one for 2 years for 3.3$ at http://cheap-web-host.net/index-2.html
Which extention are you wanting? If you want .info you can get them for $1.99 plus 20 cent ICANN fee. If you want a .com, you aren't going to find any as far as I know
