Unfortunately, the problem is

Unfortunately, the problem is that Walgreens (and every other retailer that sells these kinds of cards) is following the "law" -- the Banking Secrecy Act and the PATRIOT Act, primarily -- which requires them, under penalty of serious fines and possible arrest, to record these transactions in cash transaction reports that are sent to FinCEN.
