Just got back from my local Boots and they told me that as of tomorrow (weds), 150 or more digital photos, 6x4 size on the 24 hour service will be 4p per print. Cheapest on the high street (i think!) as Tesco and Asda are both 5p per print. Don't know if it will be available online too. Ideal if you don't want to spend time uploading over 300 images to Jessops!
Is available online but defeats the point as there's p&p to add on
