Lol, love licensing.
The one you linked gabi is only for pre-loaded pcs, kind of like oem, so wIll not be transferable and won't be manageable by a kms server etc.
The license you have quoted, is that with sa? If so it's no comparison.
You either license this stuff properly or get embarrassed when ms come knocking for an audit.
Do not piss about with licensing, just do it properly. If we aren't the reseller proving you with the price then ask us, if we are then ask us why you should buy that one and not another license scheme. There's lots to choose from, and you can't compare your price to the select price mcbunny quoted, select is for the bigger boys, bigger discounts and might not be with sa etc.
I'm sure I was told the other day that select licensing is being discontinued soon.
This is like the people who laugh at a £1000+ cost for a disk for a San when they say you can buy a terabyte disk down pc world for £50............
