I've just hidden the second button somewhere on the site in celebration of Deal Seeking Mom's birthday today! The button looks exactly like this one below, so keep your eyes open and have fun searching for it:
The first person to find this one and follow the instructions to claim their prize will win a $50 Sephora gift card. Don't worry, you still have one more chance to win after this!
Also, enter to win a $200 Amazon gift card by completing the birthday quiz!
UPDATE: This button has been found, but look for the third and final cupcake button to be hidden right around 6pm this evening!
