All I can really add is this is a good read.

My daughter just turned 4 and we want her to start sampling sports. We are looking at gymnastics and maybe swimming lessons or ice skating lessons.

Gymnastics place seems to be a cash cow. You can do a membership which is $50 fee plus $55 a month (9 month schedule). Or $65 for a sample month. Doing the math and people pay over $500 for a 4 year old to do gymnastics??? Wow...needless to say we are doing the sample package.
