Car rental coupons are great and often offer you a massive saving. There are, however a few points that you need to consider when scouting for your coupons. Not being informed can make that discounted car rental deal into something not discounted at all!

Check that the coupon is valid in the car rental location of your choice. This is a simple but frequent mistake. With larger rental groups, they have offers for specific states or regions and this could exclude you. You won't come to any harm if you do make this error, you will just feel a little sheepish. Other offers are valid as a one way rental, or only from certain cities. Getting your car rental coupon can mean a bit of research as you can see, but you can end up with some substantial savings, so read on and see what else to be on the look out for.

Ensure that the coupon is valid on the date you wish to rent. Most car rental sites update their coupons frequently, but there can always be mistakes. And sometimes discounted deals may end with out prior notice. If in doubt or you can't find a valid to date, call your local branch.

If you think you have found an unbeatable or unbelievable offer, as well as visiting the companies' homepage, also visit their forum. You will often find that any issues or hidden charges are discussed here, giving you invaluable information. There may be hidden extras or limitations to these coupons that you weren't aware of. Always get the full information before signing your agreement so that you aren't stung later on.

Check that you do not need a paper coupon as well as the online version. Most companies do not insist on a paper version, but read the small print just in case.

Also, some codes require you to become a member. This can be advantageous if you like the benefits of belonging to the group. At times however, there may be a small charge or fee. Most coupons that require membership state it clearly, but some hide it in the small print. Consider what is going to save you the most money. If you frequently need to hire a car, consider the membership, but if this is a one off, you are best to avoid these coupons.

If there are two large rental companies in your area, check to see if one the competitor will match or beat the coupon. I guarantee they will know about the offers others in the business will be offering and be desperate for your trade.

If you have found a good website offering car rental coupons, but they don't have your requirements due to limited rental days and such like, bookmark the page and visit it frequently. Most of these sites are updated on a daily basis and so the perfect coupon saving you cash could be just around the corner.
