Supermarkets such as ParknShop and Welcome in HK have their own range of products which usually have ugly packaging. Apparently there is an explanation. Seems plausible to me.
The British supermarket Tesco has a “value” line of products with infamously ugly packaging, not because good designers are unavailable but because the supermarket wants to scare away customers who would willingly spend more. “The bottom end of any market tends to get distorted,” says McManus. “The more market power firms have, the less attractive they make the cheaper products.”
