You can get the multiple accounts discount only if you purchase several web hosting accounts at once.
We have developed our pricing to be competitive in the web hosting market. We do not over-sale our servers/packages, like all big hosting companies do. To us, this is a blatant misrepresentation of their services.
Rather, we have a fair product for a fair price, and as such, we only offer a discount to those that want several web hosting accounts and purchase them all at once.
