Prison Chips
It's uncommon to hear positive things about jail meals. Prison Nutraloaf, a nutrient-dense slab of revolting mystery substance, is one such item that is regularly served as punishment to thousands of prisoners and is universally despised. What then could be so good straight out of jail that ex-cons had to start a gray market to get their hands on it once more? The entire shebang.
These potato chips, produced by Keefe Group, were designed specifically for distribution to penal establishments. The taste is similar to All-Dressed chips, which are sold in Canada. Prisoners adored them, and many were dismayed to discover that they were not available once they were released into "the real world."
A few diligent chip enthusiasts would go to prisons and purchase chips from the commissary. They might then be sold again on eBay. The only issue was that this was plainly a highly ineffective approach to contact them. The gray market was modest in size but strong. In fact, they were so effective that the business ultimately chose to expand the market and make them accessible outside of jails as well.
