Buyitultracheap is a pirate SW vendor.
Do not purchase anything from them!
Microsoft has confirmed that licence key for Office that buyitultracheap.com provided to me is fraudulent.
Don't believe all the positive reviews on this site, they are almost all certainly done by the vendor themselves and not by real customers.
The physical offices they claim to have according to their website are a call center, a mail forwarding office, and a hotel - in other words, their operation is a fake.
