As a college student, I like pizza. A lot. More then I should in fact, and therefore I order it more then I should. When I started my academic career at West Chester University, the first thing I did was look for a pizza place. What I found was a local Domino's franchise. In my experience, this Domino's has been the best national pizza chain location I have dealt with in terms of quality, consistency, and courtesy. Their food is good, consistent, and their employees are courteous and helpful.
One time when I called Domino's I listened to their recording detailing their specials, and I heard they now have online ordering. I checked it out and got hooked - now I only order online. Recently, however, Domino's did an overhaul on their online ordering system and now it is even better then before!
You start by making an account. To make an account, all you need is an address, phone number, and Email account. The phone number is so the store can confirm that this is an actual person and not a bot, and to call if there is any questions about your order. The address is the default delivery address, and the email is for order confirmations. Once you make an account, the site will suggest local store locations for you to choose from. Once you have selected a store, you can begin your order.

Once you've registered, you can start to order.
The Getting Started Screen allows you to choose whether you want to make a pizza, order a specialty pizza, order a sandwich, order sides, or use or select a coupon.
Each selection is very user friendly, and today we're going to follow a typical order of mine.

So we click on "Browse all Coupons" and we are brought to this screen.

There are usually around a dozen coupons to choose from, ranging from single person deals to enough to feed a party. Clicking on the tabs at the top lets you browse by the number of people, or you can just scroll down.
I'm going to select the 1 Large American Legends Pizza, an 8 piece bread, and a 1 liter for $18.99

Once selected, it adds the coupon to the sidebar and brings you to a screen where you can make your pizza.

Since I chose an American Legend's pizza, there are already toppings on it, but if you had chosen a regular pizza, it would just be cheese. Here you choose the type of crust you want (I'm going to choose Classic Hand-tossed) and the size (Large, since that's the coupon).
Once selected, it brings you to the topping screen.

Here I have selected the Ultimate Pepperoni Feast pizza. If this were a regular pizza, you could select the topping you want by checking the boxes to the right. If you look closely, you can see pepperoni is checked and the extra tab is chosen.
Because I have a coupon, the site automatically takes me to the next item on the coupon, but if this were a regular order, you would be taken to a page that listen all available sides to choose from. IE: Wings, breads, salads, and soda.
Here I can choose which bread I want, regular bread sticks, or cheesey bread. I'm going to get cheesey bread.

The bread is not added to the sidebar, and I have the option to remove it if I change my mind, or change sauce if I wanted to. I also now choose my beverage, which will be Coke.

Now that that is done, I'm still at the sides page, but that is just for if I wanted to add more items to my order, however, I am done, so I click "Price order" on the right under the list of my items and am given the total of my order, which is $21.98.

Once I'm sure of my order I hit "Checkout" and am brought to the final screen. This being a commercial company, they try and get me to add another item, but I refuse and just click on continue.
Here I review my order, and select payment method. You can pay by cash, credit, or with gift cards. I select my method, then scroll down and hit "Place Order" at the bottom.

After my order is processed, an Email is sent to my account confirming the order, and I am brought to this screen.

This is Domino's pizza tracker. It tries to show you the process and time it takes for your pizza to be made and deliver. It's a neat system, but only an estimate. I've had pizzas get here after it's said it was delivered. The average time it takes for a pizza to get to me is about 45 minutes. Though I've seen as short as 30 and as long as 1 and 1/2 hours, it just depends on the business of the store.
So there you go, I hope I've convinced you to try Domino's online ordering. Just be aware, your experience may very, I have a very well run franchise here.
