Yes they do have cases(actually called 'flats') of 24. More common to see the 24 cubes. I know this cause I happen to work for a major pop supplier. Won't say which one but it starts with a 'P' and ends with an 'I'
We who deliver it have noticed the increase also and feel the same pain. And before you think we get it free, we pay pretty much the same as you.They tell us cans are more expensive to produce and the profit margin isn't good on them so they don't discount them to us. Shoppers still has their 3 12pks for $11.00 and I saw Loblaws with 3 for $10.00 today. Best deals can be found in 710ml as Sobeys will probably put them on again in the summer. 6pk for $1.99 I believe. 6-710ml bottles is equal to 12-355ml cans in total volume plus you can put the cap back on
