I bought a few preventive healthcare packages from Desimd for my family. The best thing about buying the packages on this site is that I can actually compare similar packages offered by other hospitals (down to the tests they take) and go with the best value for money package or with a package that suits my needs. The site also has some good information about health related issues.
In these days of increasing medical care costs, preventive healthcare is one of the more undervalued part of system. Identifying health issues well before they become something more serious is a very cost effective method of dealing with them.
Once the sale was completed, I had no issue getting the hospital honor the commitment.
