This is a simple study that can help you save money on printed 4×6 photos.
You will need to decide if you are willing to drive to a store, and how many photos you are willing to buy.
I did not include temporary coupons, my wife says these are common. Keep an eye out for them.
If you only want to print 1 photo and are willing to drive to a store, you can use Snapfish and pickup at Walgreens or CVS.
If you want over 75 photos and want it delivered, you are probably best going to Walmart, but there might be an opportunity to save money at Snapfish given they may have coupons.
My number one suggestion is to double check the price you are paying at checkout. It seems every website would bait you in with cheap prices, only to change them at the checkout screen because you had to pay for shipping, or were picking it up in store.
