Coronavirus panic is causing one product, in particular, to become a hot commodity, especially at big box stores. Costco's toilet paper in Canada has been flying off the shelves. Now the store is even putting the in-demand item on sale.\nFrom March 2 to 15, 40 packs of Cashmere Premium 2-ply bathroom tissue are just $15.99, with a savings of five dollars.\nThis deal is available at Costco locations in Ontario, Quebec, New Brunswick, Newfoundland and Labrador, and Nova Scotia.\nResidents in the western provinces need not worry, however. In British Columbia, Alberta, Saskatchewan and Manitoba, 40 packs of Purex Premium 2-ply bathroom tissue are on sale for $16.99.\nOn top of the toilet paper sale, western Canadians can also take advantage of another useful item to have during the outbreak: Scotties Premium 2-ply facial tissues. A case with 15 boxes is $13.49 until March 15.\nPreppers who are hunkering down might also be interested in the fact that 48 packs of Duracell AA batteries are also on sale for $21.99.\nWith so many people rushing to Costco in particular for supplies, the availability of any of these items cannot be guaranteed, although you can order them online if you feel so inclined.\nToilet paper aisle at the Dufferin Mall Walmart in Toronto last evening.

And toilet paper feels like a way to maintain control over hygiene and cleanliness."\nHealth Canada has advised people to stock up, but to avoid "panic buying" in particular. They do, however, include toilet paper on their list of extra items to have at home.
