A member of Navy Federal Credit Union swipes her arm along a shelf of foot powder at a store, catching the containers in her grocery basket. She continues to shop in this fashion, dumping an entire box of beef jerky sticks into the mix. When her military husband receives the care package, he passes out its contents to fellow soldiers. The foot powder is for everyone, but the love note is clearly for him. Navy Federal Credit Union offers unlimited 1.5 percent cash back on purchases made with a cashRewards Credit Card.
