Hey there,
It's not a real affiliate incentive that we offer but you can win 1 out of 50 T-Shirts just by publishing a review about the Spreadshirt Marketplace on one of your websites.
Since I suppose many affiliates run their own blogs of some kind that might be interesting for some of you.
Please find the details at our blog
In case this offer doesn't fit in here please feel free to move it to somewhere else or close it.
Cheers
Patrick
