Ronald Reagan Forever

Stamp machines had not yet updated yesterday, so one could still purchase "Forever" stamps at $0.45 and return them today for $0.46. Not very scalable, but good for over a 2% riskless return in 24-hours. Machines had as much as $900 per post office for 2,000 stamps and a $20 return. Add to that another $9 or so for the credit card rewards.
