I shop and use their delivery service because I am in a wheelchair. I have had items out of stock and substituted. I have always been able to apply another choice. It may be a higher choice. I usually don't choose it. I get really good service and they bring my groceries inside and put them on my counter. They are always on time and sometimes early. The only complaint is by using Instacart is that they are high. Sometimes they go up every week. I am on a fixed income and this really hurts. I can't afford their price on any bacon. I have items that I can't afford, and I can't purchase them. I know that there is inflation and shortages but, the prices need adjusting. I really like Publix and I intend to keep using the delivery service.
