There are some caveats though:

1. Have an actual stock certificate sent to you -- $20
2. Stock purchase fee -- $1 per share
3. Annual stock ownership fee -- $2 per share
4. Checking the price of the stock using an online stock quote site -- $1
5. Telling anyone that you own Spirit stock -- $1 per person or $5 per group

There is a club that you can join for $9 per year that reduces the above fees by 50%
