Very good point CSSAdmin. Even though my company handles most of the support, I do get emails from time to time. But it's definitely worth the small amount of work for the payout. Here's an example here...

I offer free things for anyone who buys from my reseller store. Some people forget to pick it up from their confirmation page so they email me for help.
Again, when you are building your own customers this is a responsibility you may have. Now I didn't have to offer the freebies, but I do so to make my reseller store more appealing.
So yes, a reseller definitely requires that you have more responsibility and you play a bigger role for sure.
