I keep a little list of money saving tips that I pull out when I hit the road with my wife.
1. Pack sandwiches and fruit for the trip.
If you and a friend/partner are on a trip you're gonna eat at least 3 times a day. That'll easily set you back $40 even if its fast food. If you pack your own stuff you'll save money - and it'll be a lot healthier for you!
2. Use a GPS Navigation System
We upgraded from maps to the 21st century a couple of years ago and I think it's paid for itself in terms of not taking wrong turns!
3. Stop whenever you see Cheap Gas
Even if the tanks still half full - if you see a bargain gas price, STOP and fill 'er up!
4. Plan your hotels/motels ahead of time
We used to just drive until we were tired and stop off at the first place we found. Sometimes that would be a $150 a night hotel, but we'd be too tired to drive and find a cheaper one! If you do you planning you can almost always find somewhere to stay for less than $50!
5. Delivery a package along the route for extra cash!
. Basically - if you are planning a road trip, you plug your route into the site and it tells you if anyone along your drive has something they need delivered along your route! My wife and I had some space in the SUV so we took a parcel full of college books from a mom and drove them to her daughter studying at UT. She paid us $70 for the trouble and we made our gas money for the trip and lunch too!
6. Don't use CREDIT CARDS
Burn them, cut them, shred them. Pay for everything with your check card or with cash. DON'T use those damn cards...ever.
Hope you guys find these tips useful.
