Once the roll out to 4300 walmarts is done, if ehach store sells 100/week (about 15/day if they are open 6 days/week).
If outof the $2.49 price YOW get $2 then that will mean 4300 * 100 * $2 = $860,000/wk ==> approx $10 million / quarter.  Then you add in all the other stores. What the profit on that is is another matter but revenues may grow very quickly from here for a short while.  

Production wise 4300 * 100 * 52weeks = 22, 360, 000 units/year.   So if sales are just 100/week/store then they will need to ramp up production in the next quarter or 2 at most.
