4. Online shop as much as possible
This is how in-store shopping goes during the holidays: you go to a store with huge amounts of people, take your coat off, take your boots off, try the clothes on, realize you are still bloated and wearing long underwear, put all your layers back, see the line at cash register and go back home. Skip all of that and online shop, use your coupons and stay a happy Scrooge!
