What's the difference between refreshing my ad with Bitcoin and buying store credit?

There are 2 ways to checkout on our site:

1. Purchase refresh time directly with Bitcoin
2. Purchase credit with Bitcoin to be used for refreshing ads in the future

The benefit of buying credit is that you receive a 10% bonus for every $10 spent. Using store credit also speeds up the checkout process when refreshing your ads since it just takes a single click.
