Isn't the problem that people actually don't put up a big fuss (in practice) and that they likely would if the price rose (in theory)?
I'd certainly just prefer if they'd just increase prices naturally instead of this obfuscatory ********.
Yeah maybe it's more the media that makes a big deal out of it. I guess the point I'm making is, a specific, non essential consumer goods product X getting smaller becomes a major news item. Product X getting more expensive rarely does, you only really hear about goods that are 'essential' or used by the majority going up in price (e.g. energy, fuel) or generically that food is going up in price.
Prices sometimes stick at thresholds like £2 for simplicity, not that I necessarily think that's a good reason and don't mind rising prices. There's also some people that buy whatever they can for budget X, rather than spending whatever is necessary to acquire quantity Y. So this probably suits them, if they budget £2 for chocolate, they keep spending £2 on chocolate not £2.22 or whatever.
Disguising the price rise seems underhanded though, it's like a con for people who don't notice a product got smaller and fooling them
Maybe but packaged goods are labelled with the weight so you either notice the product is smaller or you read the label, I'd say it's a bigger issue with restaurants reducing portion sizes where it's a lot more obfuscated, you don't even get to see how big the portion is before it is served so you are kind of committed to buying it at that stage.
Shop - you can see the item prior to ordering, it is labelled with weight
Restaurant - you can't see the item prior to ordering, it often isn't labelled with weight unless it's a steak or something
In summary I think the real shrinkflation con people should be up in arms about is On Trade i.e. restaurants, takeaways etc where e.g. a "large chips" has no definition and they can just give you whatever portion size they want, much more stealthy than anything Cadbury have done.
I do understand where people are coming from about perhaps items that are sold at size X for years suddenly get smaller, and people are just buying on the assumption that the size is the same every time, but I guess maybe we just need to wise up more to what we are picking up of the shelf and make less assumptions.
