How to save our money in food?

Despite the bad crisis, we have to eat to support our lives. Most people are difficult to reduce the food cost; however, they can trim down some in food spending:
1. Planning before spending
It is better to notes what kind food that you need to buy. Do not go to the supermarket or retail stored without its notes. Most women are tempted with so many foods at the supermarket. They just grab and put it at cart. They forget that they should pay it.
With notes, a mom knows what she should buy. They just grab the food that is on the list.
2. Coupon or discount coupon
Some supermarket offers free sample product to attract a new customer. It is not much food that they offer but it could save little penny or dollar. Some company also offers 20%-80% discount for specific product. You can find the discount of the product at website, blog, facebook, or twitter.
3. Buy in bulk
Some groceries will give discount to anyone who buys in bulk. You can buy in bulk toilet meat, milk, and eggs. Do not buy in bulk fresh vegetable and fruit, unless you are sure that your family can eat all of it.
4. Buy generic food
Most food has brand that is usually more expensive than generic food. Buy generic food to trim down your expenses. Some generic food has good quality too.
5. Plant garden or create a backyard farm
Get benefit from wide backyard. Bury vegetables or fruit tree. You can harvest it when the vegetable or fruit is ripe. Some chicken are also good at backyard that can produce fresh eggs every day.
6. Consider use canned, dried, and frozen
My neighbor save goat meat at frozen for two month. The meat is still good and he cook goat Kari for us. You can also to consider frozen food. Buy the meat in bulk and put the refrigerator. You can also dried the meat with spicy that can durable for three months.
The canned food such as, fruit, vegetable, and salami is cheaper than the fresh food.
7. Buy directly from farmer
In my country, we can buy rice to the farmer directly. It is cheaper than buying rice at supermarket and groceries. We can save the supermarket or wholesale margin. In my country, the supermarket rice price is two times farmer rice price.
Perhaps your neighbor has plant garden or backyard farm. You can buy directly to them. I believe the price must be lower than supermarket or grocery.
