1) Car Rental Company Websites: This may seem like the most obvious place to look for car rental discount codes, but for one reason or another, a lot of people forget to go directly to the source when they are looking for money saving codes. On some car rental company websites, their discount codes may be prominently advertised, while others may require you to do a little bit of searching to find them.

2) Blogs: Now that it’s 2008, blogs are no longer online diaries. Instead, blogs are a way for people to quickly share information with others over the Internet. Since everyone needs rental cars when they travel, you will find lots of bloggers who share the rental discount codes they come across with their readers.

3) Forums: Forums are like the town halls of the Internet. From general forums to forums on very specific topics, you can find people who are sharing rental car codes in forums all across the web. The great thing about forums is that because so many people are contributing, the rental car codes you come across are almost always the most recent ones available, which means they will definitely work when it is time for you to checkout.
