Dealing with REI's inefficiency and unprofessionalism was a truly unpleasant experience. I paid for a 1-day delivery because I needed to get a backpack before I left the US (I was leaving in 3 days but decided to pay for the 1-day delivery to be on the safe side). After a series of mistakes from their side and UPS's I ended up without a backpack nor any valid explanation from REI. On the contrary, I felt I was being mocked by their customer service - I called and chatted so many times to ask for their help and every time they would do something useless or that negatively affected the possibility of me getting the package on time. I wasted a lot of time and energy and dealing with this and I really regret not having gone to another retailer. Although their stores look nice I would never recommend buying from them because of how horrible their customer service is.
