Yes, if its just for the blister packs, I am all for it. I hate the ones in which Sandisk SD cards come in. It takes me 10 minutes to open those packs, using scissors! And I am lucky if I manage not to nick myself in the finger with the plastic.
Anyway, I too am someone who sells his old gadgets/things pretty often. It's the only way to remain on the cutting edge without being loaded with cash.
And like you, Jason, I always provide the original packaging with the product. Guess if its for all products, I'll have to provide a general brown box and say that was the original packaging
I do agree on the environment friendly part of it, of course.
