My daughter gets her toilet paper online with Amazon shop and save - comparable with Sams or Costco. If you have five items in a shipment, you save 20%, no shipping. Of course, for us, Costco is a mile away. We even get our gas there.
It’s amazing what you can get at Amazon. A neighbor gets 40lb bags of clumping cat litter. Good price and free shipping with a Amazon Prime subscription - delivered right to their door by a long suffering UPS guy.
