These days, expenses need to be held to a minimum because money has become a very precious commodity which is also very scarce.  If you are living on a fixed income, it is necessary that you find ways in order to cut corners such as transportation or gas. 
One of the simplest ways to cut back on your transportation expenses is to make the most out of yoru grocery trips.  Here is how:

1.    Make a list of all things you need.  One of the most common problems when people do not make a list is that they forget something, in which case they will have to make yet another trip which is a waste of time and gas money.  Make a list of what you will need for an entire week so you will only need to make 4 trips to the grocery every month.
2.    Use coupons.  There is no shame in clipping coupons, much less in using them.  If you are operating on a tight budget, you will need to find clever ways to make ends meet and coupons are like great bonuses for being a perpetual grocery shopper.
3.    Take your family with you when shopping.  Most moms and dads would prefer to leave the kids in front of the TV when they do their grocery shopping thinking that it would be most efficient that way.  However, if you look at it a little closer, taking your kids would actually be more practical because it would be like a little family outing (sans the expenses)  plus you will have more hands to carry the grocery bags.
4.    Take your time to look around.  There might be some things that you will not be able to afford at the moment but you can on the next pay check.  What you do is to look around for those things and write them down for your next trip.  This would make your next trip more efficient since you already have a list going.
5.    Compare products and prices.  Just because you have been buying and using the same brand for many years does not mean that you have to stick to it forever.  It is good to look for what else is there since it is highly likely that you will find something better or at least cheaper.
