On the 'Compare Our Products' page, VPS is listed as 'starting' at $15 per month. But down below, it says you are also required to have at least shared hosting of mysql at $9.95/month.
Unfortunately, that means it's not fully VPS, nor is it really $15/month. To get files hosted on VPS and shared mysql, you must spend no less than $15.00 + $9.95 per month or at least $24.95 per month or about $300 per year.
It's also not made clear that more often than not, you'll probably end up needing mysql vps which will not ever capable of being at the lowest tier ($15/month), but actually probably somewhere above that, closer to $20/month. Now, you'll want to make sure your memory dynamically changes to handle traffic, so when it spikes, you'll end up pushing your cost from files VPS higher.
In essense, you're likely to end up spending at least $38/month (probably more) on a product that is advertised as $15/month. While the truth is there in the fine print, the pricing is misleading and seems designed to close a sale without thought for the outcome when budgets are blown.
Top that off with the fact that even with shared mysql, it's not technically fully VPS. It's a hybrid. That distinction is pretty muddy on this page and others.
I'd like to see this advertised in a cleaner, more transparent manner. If you're going to be clean and green, DH, let's do it on all levels.
