Hi lorenkjr1,
Skype itself is an free. If you don’t get phone number and you only pay for the seconds you spend talking to someone.
If you're in the US you can get unlimited calls in one country of your choice for $2.95 a month, $5.95 and only landlines if you're in Europe (I know, sucks for us right).
Getting your own number seems to cost $18 for 3 months, but the above offer seems to include voicemail, which is a little strange.
The prices vary depending on where you are and who you want to call, so you're better off just going to skype.com and clicking the options that apply to you. Giving you all the options without knowing where you are and what you want to do would be a little pointless. Signing up at skype.com is free.
