I live about 3 hours from my nearest apple store (Dallas, TX). I thought about driving over there this weekend to try to get an iPhone 11 and trade in my iPhone 7+ in person so i don't have to ship it and deal with potential damages. Is this feasible? I'm not sure of what the demand for the Iphone 11 is, or if you can even just walk into the store and purchase them without some sort of pre-order. Any help is greatly appreciated, thanks!
