Sponsorship is completely free, unless you like to help a college student out, then it's $5. But if you just want to swap buttons, I'm totally down with that. Just go to my sponsor page and you'll find passionfruit. If we swapped buttons this month and you would like to renew, email me: email@example.com and I'll renew your button on September 1st.
I look forward swapping and sponsoring you next month!
P.S Look out for the August Sponsor giveaway later today.
