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.
