While some things may be nice to do, others may be imperative particularly when they impact the customer. The image you and your employees project can have a big impact and when things get hectic, don't forget about the customers point of view. The customers don't need you, but you need the customers. A walk down the produce section of any grocery store will convince you that there is lots of competition for consumers. You can't compete with the large chains on price, nor should you try.
Price is far down the list of reasons that customers buy from producers.
Emphasis is on freshness, quality, the on-farm experience, etc. As every survey tells us, consumers are looking for more convenience in their purchases. Notice the pre-cut salads, packaged produce, etc. Think what you can do as a marketer to capitalize on this. You might even consider selling packaged mix for muffins so that all the consumer has to do is mix your berries with the muffin mix for fresh blueberry muffins.
