Walgreens, a popular pharmacy chain, has received mixed reviews from customers. While some had a positive experience with quick and smooth service for flu vaccines and COVID boosters, others faced challenges with FedEx package drop-off and limited pharmacy hours. The store's cleanliness was also noted as an area for improvement. However, the convenience of the mobile app and in-store pickup was appreciated by customers. Overall, Walgreens seems to provide a varied level of service, with attentive staff, but also some operational challenges in certain locations.
