Summarize this article:

Today, a wide variety of sites selling cigarettes exist online. Using a simply query like "cigarettes online" in your preferred search engine should yield dozens of relevant results. Each site may have its own selection of brands, products, and accessories for you to browse, so you may want to look at a few sites before making your decision. When you've found an online cigarette vendor that you like, browse through the cigarettes available to find your preferred brand(s). Most cigarette sites will carry most popular, well-known brands like Marlboro, Camel, etc., while some will have foreign or exotic varieties for sale. Generally, cigarette sites will have a prominent list of the brands offered in their "Cigarettes" section. Many cigarette sites will also have a search bar (usually located in one of the page's upper corners) that allows you to search for your desired products. When you've found some cigarettes you like, look for an "Add to cart" button on the page. This will usually be prominently located near the picture or title of the product you're interested in buying. Clicking this button adds the product to your online "cart", which is a running tally of the products you intend to purchase. Nearly all online retail sites, from enormous ones like Amazon.com to the smallest independent retailers, use this "Add to cart" system. Adding items to your cart doesn't purchase them right away, so there's no need to worry if you accidentally add the wrong cigarettes to your cart. When you've added all of the cigarettes you'd like to buy to your cart, look for a button somewhere on the page that says "Proceed to checkout". This will take you to a series of screens where you'll confirm and finalize your purchase. You'll also have the option to eliminate items from your order, if you'd like. Note that some sites may require you to sign up with an account before you can check out and purchase your cigarettes. During the checkout process, you'll be asked for certain pieces of personal information so that the cigarettes can be paid for and shipped to you. You'll want to have a valid credit handy and to be sure of your billing and shipping addresses so that you'll be able to supply this information easily. Fill out the information in the appropriate text boxes, then proceed to the next page. Be wary of scam sites that may try to rob you of important personal data. While most online retailers will require your credit card information and address to buy cigarettes, you should never have to supply your social security number or bank account information. If you are asked for this, leave the site immediately. If you want to get your cigarettes as quickly as possible, you may want to opt for a special shipping option. If this is available, it will usually be offered to you during the checkout process. Some sites may offer options as quick as next-day shipping, though these can become quite pricey, so weigh your desire to get your cigarettes quickly against the cash you have to spend before making a decision. At the end of the checkout process, you'll be given a breakdown of your entire order everything you're about to buy, the shipping options you've chosen, the address your order will be shipped to, and so on. At this point, you'll want to ensure that everything in your order is correct, because it can be tricky to cancel an order and receive a refund with online shopping. When you've finished reviewing your order, confirm it to make the purchase. There will usually be a prominent button near the bottom your order labeled "Confirm" or "Finalize". Congratulations! You've just purchased cigarettes online. After making your purchase, all you'll need to do is sit back and wait. Your cigarettes should arrive within the time frame specified by the vendor. If they don't, you may need to contact the vendor to receive an update on the status of your order or request a refund. Contact information should be available on the site you purchased your cigarettes from.

Summary:
Visit a cigarette retail site. Browse the site's selection of cigarettes. Add cigarettes to your cart. Proceed to the checkout process. Supply relevant personal information. If desired, choose an expedited shipping option. Review and confirm your order. Wait for your cigarettes to arrive.
