If you are planning a trip and trying to find the best deal on a rental car, things can get a little confusing. Although there are plenty of great price comparison websites which will help you narrow down your options, when you start applying different car rental discount codes, it can get a little confusing to keep track of which one is actually going to save you the most money.
To help you figure out what you’re doing, I thought it would be useful to look at a real example. Let’s say that you are traveling to Salt Lake City for ten days between September 12th and 22nd. Since it’s just you, or you and one other person, you are looking for a compact car. Now, after doing some comparisons, here are the results you would get for that trip:
Alamo
ID # 428448 Cpn AD6974JDM ($25 off) $267.76
ID # 7014136 Cpn AD6974JDM ($25 off) $267.76
