The most interesting thing that you may have overlooked about Walmart's purchases last March, is that it appears with 1 month of Walmart purchases included in the Q, ROX's revenue per GGB case remained above $14. Largely similar to what it had been prior to the Walmart deal.
That indicates to me that Walmart is paying approximately, the same average price per case that other distributors and supermarkets are paying.
Every additional case sold collectively by the 10,000* high velocity supermarkets and Walmart, per store, per week adds approximately $1,820,000 per quarter.
