Note that this most likely not Ubest's pricing decision, but the convenience store or grocer retailer that sells the product to the end consumer.
Though I guess it's just a ploy by the retailer. Perhaps they are trying to hit certain magic price points. (Like 0.99 of local currency.)
You can see the same for the fixed price chickens vs the organic/free-range that are priced by weight.
Although Tesco will no doubt try to game the system, it is in their interest to show you understandable unit prices because they want to flog their stuff cheaper than the brands.

I'm not sure Tesco makes more money on the cheaper stuff. People who care about price and quality go to Lidl and Aldi anyway (if available in the vicinity).
