Every Walmart is exactly the same and you either love or hate the place, so I won't waste your time by talking about the cheap groceries, etc.
THIS REVIEW is strictly for the Photo Developing area, which is amazing. When Oakville Place Blacks took one hour to develop ONE 8x10 photo from the kiosk, and gave us a photo with the head cropped off, we had to make a quick detour to Walmart to remedy the situation (It would've taken 1.5 hrs to reprint at Blacks because "that' just how long it takes"). At Walmart, our new photo printed in seconds and looked much better than Blacks. You can pay at the photo area, and they have a very helpful staff member showing people how to use the self-serve machines so that you don't have to wait too long. Very good service and much more useful than a professional store.
