- ❓ When I click on Kerish Doctor 3 Year 3 Pcs - On buy screen (Order.mycommerce.com) it shows Kerish Doctor for 4 Years. Is this valid for 3 pcs and 4 years If I buy now from colormango?
Answer
- Yes, at the moment Kerish Doctor is offering a New Year Special Deal: Buy now and Get +1 Year for Free. So if you purchase the 3-Year 3PCs license now from ColorMango, you can get a license key for 4 Years. This special offer is for a limited time only.If you have any further questions, please let me know.
- ❓ I am using Kerish Doctor 4.95 now and subscription is active till 1 Jan 2024. Can I buy Kerish Doctor 3 PCs 3 years now and activate on 1 Jan 2024 and will remain valid for 3 years?
Answer
- Thank you for the question. However, the license key is valid from the moment it is generated and delivered to your email address.

We suggest you repurchase it around 1 Jan 2024.If you have any other questions, please let me know.
