One way I save a lot of time and energy is by having a storage/stock room where we store consumable items we buy regularly. Not only does this save us time by not having to go to the store, but we also can avoid other impulse purchases, have it delivered to our home, and get to spend more time with our family.
What to put in your stock room? Things you use daily, like shampoo and conditioner, soap, toothpaste, etc.
If you use a subscription service (like Subscribe and Save through Amazon or Target Subscriptions), you’re already doing great by ordering somewhat ‘just in time’. To improve on this, just fine-tune what you order.
