Walmart Nogales El Greco is a mixed shopping experience for customers. While many appreciate the reasonable prices and the convenience of services like pick-up and delivery, there are notable challenges. Customers often find that self-checkout lines can be long and inefficient, with machines frequently experiencing issues. The parking situation is also problematic, as it can become congested and may require payment, even with validation. On a positive note, some employees, particularly in the shipment area, have been praised for their proactive and efficient service. However, experiences at the pharmacy can vary, with some customers reporting rude interactions. Overall, this Walmart location has both strengths and weaknesses, leading to a neutral impression among shoppers.
