On the last point, Only way I can see it working is if the club buys the stock to allow local business to cater inside the ground as it's a huge risk to the likes of Meat: Stack/Anarchy to have to provide for an unknown sales volume.
Which at that stage, the club will be able to get it cheaper from other companies that have far more production capacity. The only 'local' business that immediately springs to mind that could accommodate such a risk is Greggs.
