I must say that the mods are excellent and cant find any problem with it. The only problem that I do have is the fact that one buy a single site license but cant use the license when changing domains. I have decided to remove all my ilbellodelweb mods from my previous website and requested a transfer of rights. Unfortunately it was rejected. This sucks BIG TIME. I mean a single site is a single site. Yeah I have a few of their products and now a total loss because I cant use it. I didn't realize see more this policy before purchase. I will think long and hard before purchase again. Please mention these rights on your product pages so customers can see these things before purchase you mods. I am satisfied for the mods, but not with the fact that a single site license cant be transferred to a new domain. I mean really, what is the difference?
The policy has always been on the market of each module.
Unfortunately, buyers often tend evidently little to the commercial.

The license is for a specific domain. In the post of each module is also present the information about the discount for owners of multiple domains.

The license is activated on the domain, not on the site. In addition, you can read also this blog post:

Again, read the terms carefully before buying. Not after.
Finally, we reiterate that it is possible to obtain an additional license to test the modules in an installation demo on condition that it is installed in a subdomain (for example http://mybeta.mysite.com , when the domain is http://www.mysite.com) or a subfolder (eg www.mysite.com / mybeta).
For each domain, you must acquire a license.
