Buying pet supplies, such as crates, dishes, leashes, and toys, from a pet store usually makes more sense than purchasing them from a department store. The selection is usually larger at a pet store and these items are usually less expensive there. In addition, food and treats usually sit on the shelf for a shorter period, ensuring a fresher product.
Pet stores often sell a variety of bulk pet treats by the pound from open canisters. The advantage to purchasing these treats over packaged treats is that you the customer can see what is being purchased. It is important to buy only those treats that will be used quickly, however, because treats left in the open air may go stale more quickly than those treats that are protected by packages.
