Same as past deal - https://www.ozbargain.com.au/node/293089 - so just read discussion over there.
If you only pay for a month, you'll pay full price after the first month. If you want a whole year for $3.60 you'll have to pre-pay for the whole year.
Personally I starting using free 000webhost again for a quick Wordpress testing environment. This deal is more useful for production environments.
