Anecdotally, this fits with my observations at the grocery store in Canada. All the regularly priced milk, chicken, and eggs were sold out around March 25th but the "organic" milk and chicken at double the price was still in stock as was the AAA steak and the expensive Omega-3 eggs. It appears there is still a fair amount of price elasticity of demand even in a pandemic.
