I was doing some shopping for groceries today at the stores around the neighborhood and it was so amazing to see how much one could save if they spent a little time going to different stores to buy particular items as opposed to the convenience of buying it all from one place. For example, at the largest store a dozen eggs were about $4 each. Just by walking about five blocks down the road you could get the exact same product where that store sold the item for about $2 each.
Other items like juices were the same story. Virtually every store sold the exact same item at different prices. For example, one place had a special where you could buy two cartons for $3, another place had it for $2.69 per carton and a different store had it for 99 cents each. That was quite a substantial difference. I usually store hop like this whenever possible to try and get the best deals.
As you do it more often too you can usually tell what items will more likely to go on sale at which places to help you find those bargains faster.
