You need to carefully read the PR.
It states that BCCI's chosen Mexico distributor distributes products to WalMart, 7-11, etc. through an affiliate.
It does NOT state that any of those retailers have agreed to take the company's k-cups.
Thus, pps/volume response to this PR has been nominal, as it is a simple re-issue of the March PR, with no published progress made on actually finding a retailer to carry the k-cups, in Mexico or otherwise.
