Of course the most famous marketing campaign for Oscar Meyer was the Wiener-Mobile. Lowes could have their own version of this emphasizing their "Sausage Works" or "Chicken Kitchen" (tweaking it of course, not copying it). Just an idea!
Techniques like this could be used to promote their new “renovations” and methods of rebranding Lowes that current and new customers don’t know about yet once the new stores open. They could advertise in-store regarding their store greenhouse, informing of local producers currently at the “demo table”, pods, and specials so they’ll be informed in a way that gets them excited to come back.
Although this method would take more time and money it could be tweaked to bring in prospective customers who don’t know that Lowes typically has prices 3-5% lower then competitors. The displays offer a 2-dimensional display of typical products at Lowes with a QR code to scan for price compared to competitors. This will give an opportunity for onlookers to find out right then and there, and maybe even order some stuff!
Lays used this tactic to portray that their potatoes are "grown closer than you think". This could be tweaked to illustrate the freshness of Lowes produce.
With the "Family owned, fresh from the farm" concept in mind, each succulent fruit can have a sticker advertising Lowes fresh-not-frozen produce. This will give extra apple appeal to ads that might otherwise be, shall we say, the pits.
In order to appeal to their "local" new brand value, Lowes could give back to the community and supporting it. Half of certain products will be donated to charities or the homeless. This will hopefully reach prospective customers through major PR attention.
Building onto Sausage Works, this method could be used to emphasize the "#1 spot for sausage - not only in North Carolina - in the entire USA". The sausage links could be rolled up in the shape of the spare tire.
Techniques similar to this could be used to offer in-store coupons and create interaction with customers (whether current or prospective). Doesn't have to be fish (even though it works perfectly), could be used for chicken or sausage as well to build on the "freshness" factor.
Not exactly a conventional guerrilla technique, but billboards like this could be used to draw attention to the fresh produce and overall "Family owned, fresh from the farm" concept.
Not necessarily having to be presented with the same copy, but this technique could be used to focus on the coffee pods and how they offer the 'latest and greatest" coffee available.
