May 25, 2006 - Thursday. Would you believe it but they both arrived at the same time. So I can't rate one over the other for speed. There goes one test.
The price comparison was easy. Photoworks charges more for each photo (0.15) and for shipping (2.90) versus Snapfish (0.12/photo) and 2.05 for shipping. Snapfish wins.
Quality? I really made a mess of this one. The bunch of photos that I uploaded to Snapfish were cropped and reduced in all sorts of manner while the ones uploaded to Photoworks were a homogenous bunch of fairly high quality digital images. As such the Photoworks release appears to be of better quality but when comparing like with like (i.e. the Snapfish that I didn't bugger up) the quality appears to be the same.
Given that all was equal except the price means that Snapfish win. Both shipping and photo prices are cheaper.
Well done Snapfish. Take the rest of the day off.
