Ha! An article published by the Get Rich Slowly blog about how they're changing product sizes without changing prices, struck a nerve with me.
Once, I purchased a bottle of Dawn "Ultra" dish washing detergent, which was being sold in a much smaller bottle than their regular offering. The bottle screamed that you the consumer could now "USE LESS DETERGENT" (per load of dishes). I thought that was great until I got home and thought about it.
How do you use less than a squirt?
The bottle had an 800 number to the Dawn people, so for only the second or third time in my entire life, I actually used such a number to ask them. I asked the woman who eventually answered, "How do you use less than a squirt?".
The customer service rep appeared to think about it for a second. I actually believe she consulted a knowledgebase. Finally she came back with a sudden "Oh!," and explained, "The hole is smaller".
I tipped the bottle and looked at the hole and maybe it was smaller than before, and maybe it wasn't. I had never noticed hole sizes before. But, in any event, I said, "Oh, okay, thanks!".
A few weeks later they sent me a coupon for a free bottle of Dawn.
