Q: Why order photo prints in iPhoto?

I love iPhoto, and i really enjoy making books using it as well. I want to start ordering just normal 4x6 prints to keep as archived photos. But my problem is the pricing. Is there any justification to ordering 4x6 prints using iPhoto over ordering them from Walgreens?

Sure it's .12 a print with iPhoto, and it's .20 a print with Walgreens, but Apple charges 3.99 for shipping, and then .25 for tax.

Can someone explain to me why I'd pay this much for prints? The only time I guess I'd save money is if I had an order with over 70 prints; that way the charge for shipping and tax would be made up by the cheaper prints.

Does anyone else see the problem here? Or does anyone on here actually order prints from iPhoto? What are your experiences like? Pros and Cons from just uploading to Walgreens and picking them up? Is there a big difference in print quality?

Just curious. I love Apple products and I love using them, but this option just seems like it's not worth it to anyone
