Don't try to go to the Sacred Grocery Store without a wallet. The mean old guy outside will tell you you're not well equipped and send you away until you have one. When you're inside, stand next to a shopping cart and press tendon to move your arms and grab it. Push it 2 steps forward and then 20 steps to the right. From there, fight off lousy deals with your price comparing device. When you find the right one, choose it.
