I would say Id prefer higher price to keep the pack size the same. But for junk food the increased price is not attractive as they are already overly expensive. I almost 95% of the time only ever buy junk food when it is on some kind of special, so an increase wont affect me if the special price is still good. They know this is probably how most people purchase junkfoods, so they reduce the amount in the packet to ensure they maintain their profits. For me this makes sense really, but I prefer packaging to stay the same size.
For fast food like Mcdonalds, damn their burgers are small!, the portion size of chips at KFC is ridiculously small! they call these meals when really they are just a snack!!!![]()
