How long does it take to get my order?
Most orders are delivered within minutes, although verification or payment checks can occasionally add some delay.
Do we ship by post?

How can I download/view my code/key?

Are there subscription fees for your product keys?

Can I redeem/activate my product key later?
Usually yes, but activating sooner is still the safer option so you can confirm everything is working while the order is fresh.

No Retal
la licencia se pierde cuando cambias la placa base y no deberia ser asi, cuando la licencia es RETAIL.
The license is lost when you change the motherboard and it shouldn’t be like that, when the license is RETAIL.

Great Service
If you need Office (or Adobe Acrobat, which is absurdly overpriced), I’ve purchased a number of keys from Royal and never had a single problem.

direcktly and quickly delivered
The key was delivered immediately. It could be activated directly online, not over the phone, which made the whole process much more pleasant.
Once again, there was a problem with the downloads. First of all, I couldn’t find the link that applied to me directly and clearly. Then you can’t select the right language, you always get the US-American one. – I’m not sure whether the initial activation must be carried out with the US-American version or whether you can start immediately with a national/regional version. If you have a fixed data volume for the period, you don’t want to download 5GB twice. With unlimited data volume, this is of course less of a problem.
