I have been searching for Dr. Pepper in Panama since I heard that it was in Panama City. I originally heard that El Rey carried it, but I have looked in two El Rey stores in PC and neither had it. Today I received an email with the names of the stores that do carry it. Here is the email.
Dr. Pepper is sold here in the Capital at FOOD MART for $2.95 6/pk 12oz can from the USA. Food Mart as two stores, one on Via Brasil down from Price Mart, their telephone number is 214-7039 and the other store is located on Tumba Muerto (Via Ricardo Alfaro) in the Plaza Mirage and their telephone number is 236-9164.
Now that I know where it is, I will stock up on my next trip to Panama City.
Thank you to the individual that sent me the email.
