Edit Reason: minor grammar
Here is my definition.
Nulled means that license function is either disabled or edited in a way that license function is bypassed, thus being able to use the software to the fullest without any cost being involved.
Retail means that it is directly from the vendor, and is not modified. Which means that license functions, other functions are not disabled, and license should be provided in order for the software to function.
Just be aware, some nulled software, scripts contain backdoors or malicious codes that steals users' sensitive information. Only download from the person / place you trust.
Retail = Original version without any modifications, directly received from the creator.
Nulled = Removed licensing or bypass licensing, sometimes code modifications, removed callbacks ect
It always depends on the script you're using. If you're just using a HTML template, it doesn't matter if you're using a retail version, because they don't have callbacks. For scripts, it's better to use a nulled version to be safe. (As long as your hosting allows it of course.) Like simdol8080 said, be sure to download nulled versions from places you trust.
