If you start shopping early for gifts, not keeping track of what you already bought and then finding you have too many items purchased for one person and nothing for another
Not spreading out your spending and taking advantage of sales throughout the year
Not taking advantage of after the holiday sales to stock up on wrapping paper, gift boxes, ribbons, tags etc. at up to a 90% savings, and then holding it for next year.
You think you can get a better buy if you wait until the last minute, but then find there’s little to nothing left.
