Not only is this shitty shrinkflation, it is using extra plastic for a need that is not there and creating twice as much plastic waste as necessary. If we can change the way packaging is allowed to be made to fit a product then they wouldn’t be able to pull this shit so easily to begin with.
The extra air is to keep the chips from getting crushed and breaking in transport, and other lies we tell ourselves to not feel the crushing weight of being ripped off at every turn.
They sell this brand at Costco. Was this purchased from there? Will make sure to complain to their CS if so. They are usually better about this kind of thing.
My mom pointed out the exact same thing to me with the bottle of a different brand that she got at the store this weekend. I'm sure it was just coincidence that the previously non-deceptive size bottle was out of stock.
