I cannot pull actual numbers but I can tell you, 2.85 sells rarely.
When I first started here about a year and a half ago we had a couple of racks of 2.85 in the warehouse. we are down now to less than 1. Slowly its starting to get pretty thin.
I sill have a couple of rolls of 2.85 at my house as my first machine was 2.85 but that quickly changed when I found the color variations were much better in 1.75
