The shelves in most supermarkets are full of family-size this and multi-buy that. However, if you're shopping for one, buying extra (benefit) from price reductions doesn't make sense. Either your shopping is then too heavy to carry home you can't use what you've bought while it's still fresh.
Of course, shops are not charities — they price goods in the way will make them the most money. If most of their customers are happy to buy larger quantities, that's they'll promote. But that leaves the solo (单独) customers out of pocket and disappointed.
Many supermarkets are no longer doing "buy one get one free" promotions because of the (criticize) that they lead to waste. Consumers prefer money off individual items. However, though it's nice to get a few cents off a pack of sausages, it would help even more if they could sometimes (offer) in smaller packs. Even the biggest sausage fan doesn't want to eat them every day.
If your supermarket sells loose produce, then buying smaller quantities is easier. Over the last two years, some supermarkets (start) selling chicken or salad in packs (design) with two halves containing separate portions (份). Then, when you use one section, other stays fresh.
Who knows, perhaps some of the more forward-looking (one) may yet come out with a whole range of "just for you" pack sizes with special offers as well.
