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?

Key doesn’t work
Just bought the key cause I saw this web recommended.
It didn’t work (Error code upon activation: TOKEN_NOT_FOUND). Tried to email the supposed support, and didn’t receive an answer either. Glad I didn’t support the “RoyalCDKeys Team” upon purchase.

Doesnt Work properly
I had bought the same key for 2019 version and it worked flawlessly. This one doesnt activate on the microsoft page, it says it is destroyed or used.
You can download the img from the reciept and it works, but you need to disable internet access and the pop ups still appear while offline.
It has the classic cracked office flaws, unlike the 2019 version which works perfectly
