Get 10 Free: You get 10 free prints credited when you create an account. Go to:
http://cvs.pnimedia.com/account/register.aspx Click on Start Now to create an account with your email and ExtraCare Number. (If you do'nt have an ExtraCare Card, pick one up at CVS or have mailed at CVS.com). Do this before the 30 below, and CVS will send you an email crediting you with 10.
Get 30 More Free: Then, to get 30 more credited (or go here first if you have created an account before)
http://cvs.pnimedia.com/extracare_signup.aspx.
Get 10 More :Free Then under Order Prints, click on the "Do More with Your Photos" on the right side of the screen. A new window then opens that shows 10 more free prints have been credited.
This makes a total of 50 free prints that should be credited to your account, to save until you order photos. If you order photos now, there are 2 more deals.
Current photo specials are 10 cents a print (if you order to pick up in days - the last time this took a week for me). And, whether you order 10 cents a print in days (10 cents good until 7/11)
or 19 cents a print in hours, when you buy 30, you get the next 10 free. (Get 40, Pay for 30). To do this use code SUMPRO when you checkout. Code good until July 28. (JUST CONFIRMED: for every 40 prints you order, you get 10 free, i.e., Order 170 prints, get 50 free on above signups; 120 prints remain; then, get 30 more free using SUMPRO code. Total with all promos: $9.00 for 170 prints).
Bottom line, you can get 50 free prints without paying anything. Or 90 prints for $3.00 in days.
