However buying at third party also means its likely locked to the carrier. Not sure about walk ins but afaik best buy does not sell outfight just yet. Last i checked was recent. Unless they lifted that. Its better to buy it directly from apple store as those are unlocked and can be used in OP country.One thing that may be helpful for you to know is that in the U.S. there are other retailers that also sell the iPhone and have in store purchase options. Best Buy, Walmart, and Target all sell iPhones. One of the Best Buy stores in my area of the country (not Florida) recently showed as having the 13 Pro available for pickup on their website.
