I read a bit about marketing in Latin America, during times of hyper-inflation.
Bolivia, Argentina, etc.
As I recall, long term "branding" was OUT. The need for immediate action was IN.
Direct marketing was in, as you could change prices as needed, daily if need be.
Keeping 3 sets of books was important... one in the official currency... one in the black market currency... and I forgot the 3rd one.
Commodities were HOT.
Regulations were UNBEARABLE.
