For shoppers:
This would be an awesome product IF the OBJ had been separate items, the texture files transferred correctly, and so many other things. It looks amazing in blender, but take it out of blender, or try exporting the pieces for a different render program (i.e. daz studio) and you're going to have a very hard time with it. Fortunately for me, I had a friend who could take it all apart for me and fix it, but a lot of people don't.
For OP:
If you could possibly separate out the Objects: so there is one chip OBJ, one Bag obj, and one bowl of chips OBJ, and that the textures work outside of blender, this would be amazing, and worth more than $5
