There's also the possibility of depleating a store's inventory,
virtually. Not only would that cause problems at the registers, but
a number of man-hours going through the entire stock to repopulate

I think what would be even worse is forging credit approvals. Let say
you
had a credit card and it was dead or expired. Im sure with enough

could forge approvals into their wlan. That seems very possible.

You could contact an investigative journalist, even anonymously.
Assuming your motives are to protect ignorant customers' CC numbers,
rather than extortion, you'd probably get a fair hearing.

Search for "whistleblowers guide" on Google :)
