Canned goods are usually stored on grocery-store shelves by type of food: for example, all canned vegetables will be in one aisle and all canned fruits in another aisle.
Read the grocery-store locator-signs or ask a grocery-store clerk to help you find the canned olives that are available.
Find the type of olives you want to buy: green or black.
If you are looking for ingredients for a green salad, buy green olives. If you are making enchiladas, buy black olives.
Look at the can sizes and prices to get the best buy.
If you plan to make enchiladas tonight and tacos on Friday, buy a large can.
Select a can and look at it carefully to be sure it has no dents.
A can with a dent might have a broken seal.
Put the can in your shopping cart, finish your shopping, and check out.
