Grocery stores are obviously a necessity for people. And, though sometimes they're chosen for the prices (or what's being sold), typically they are frequented just out of convenience and location. Here's an easy idea, and great way, to not only endear your locals, but create enough buzz to bring in new customers: have, within certain aisles, a display that's changed every week (how much these buyers typically shop), giving tips on how to use specific items within that aisle. This would be much different than those "recipe tips", and "advertisements", you see given by manufacturers; it would be seen as a gift from your store to its customers. These aids should include a variety of specific, and broad based, information about a number of different things your store sells (e.g.- recipe tips on italian spices within the pasta aisle, tips on feeding babies within the baby food aisle, a "how to ease a cold" tip in the pharmaceutical department, tips on how to pick produce in the produce department, tips on grilling temperatures in the meat department, etc. etc..). Make sure you also include a variety of aisles and departments in the store (broadens your appeal to a larger diversity of customers based on what they're shopping for). And, try invoking humor into some of these displays. Instead of just having advice, possibly ad some funny fact about an item sold in that aisle (giving some added attention and appeal.) I understand that to many these "advisements" may seem a little costly and time consuming for the store to produce. But, the simple novelty will leave a memory with those who see them, and impress many as well. Some will gain an appreciation, and enjoy shopping at your store solely based on these tips (which could help them either consider, or maintain, there status as a regular customer.) Also, these displays could help create that "watercooler effect" in getting people talking about your store (especially if your offering excellent advice). So, even though the costs should be considered; what's also important is being able to really "stand out" in a business where most of your competitors time is spent on the selling of goods, rather than selling those goods alongside the shopping experience.
