When you get bitcoin if you are not sending directly to us you will need to have a bitcoin wallet. You can always save any leftover for future purchases.
Here are our wallet suggestions:
For a mobile phone we recommend Blockchain and Mycelium
For your computer we recommend Electrum
For an online wallet we recommend Green address
All of these will work fine but make sure that you have a GOOD password and that you REMEMBER it! You can lose all your bitcoin if you forget your password!
