I'm not sure if this has been covered, and I'm sure as hell not going to wade through comments in the four-digit range, but there are a couple of ways to get your money's worth.
One is to buy a nonstandard caret. You hear .75 caret, 1 caret, .5 carets, like nature and jewelers worked on a rational number system. But people go in and want to buy the nice round numbers. So there is less demand for the odd chickens... you might be able to get the .73, for example, for quite a bit less than the .75.
I'm sure there are others.
