I recently had to purchase some stock photos, and found one I liked. I was about to buy it, when I realized that many different stock photo sites carry the same image.
So I spent some time finding that image on many of the big stock photo sites, and working out the price for the exact same (or similar) sized image.
* Price in dollars calculated from the cheapest “one time credits” purchase option. For instance, if a site sells 40 credits for $48 as it’s lowest tier, I used $1.20 per credit as the price.
I ended up purchasing from CanStockPhoto. I bought 15 credits for $9, which got me 3 Extra Large photos at 5 credits each.
