I recently, as a small experiment, setup shop using the Ko-fi platform, you can tip me $5.00 and it will go towards my hosting costs. If I get enough tips they will contribute to purchasing more silver gelatin paper and film both 120 and 5×4 inches and my server costs. I chose Ko-Fi because their setup was easy and fast and they only take 5% on sales, they take nothing on tips. Sadly the lowest I could set the tip jar to was $5.00.
I also have at this stage a single members tier, for those who want to purchase a silver gelatin print from this album on flickr.
There is an easy button on the bottom left of the screen that helps, too I hope?
