Skittles, vendstars, and profit margins

[CJvending]

I'am going to vend Skittles, through my Vendstar 6000. How many pieces should I aim for (from any machine) to achieve a decent (68% and above) profit margin? And what wheel setting do you suggest in the vendstar? Im already vending db cotton candy bite sized pieces and polar mint gum at setting 2 which vends about 7-10 pieces and gives me a very good profit margin.

Skittles:  I try to vend around 10-12 pieces.  They're cheap so you should be safe giving 12 per quarter.

12-14 is recommended.

I think I set my skittle vendstar wheels at 3. It could be 4.
