http://purse.io/ may be what you want. And if you are buying another Dell, well they take bitcoin!
Yea purse.io is the place. I believe they also offer a 8% discount if you buy with bitcoins.
But he want more than 30% discount. That still not enough to buy
Funnily enough I just got an email from purse saying they've removed restrictions and levels. So now "level 1s" can buy with a 50% discount.
