Samsung - Purchased a samsung galaxy a3 core for r 2299,90.

Purchased a phone for R 2299,90 unfortunately, when I returned to the office, I discovered alternative stores such as were selling the same device in the region of R 1300-R 1400. I can not understand why there is such a huge discrepancy in pricing. I spent almost R 1000 more if I had purchased elsewhere. What is the remedy for the consumer.
the phone was purchased at one of the jet stores along kingsway road maseru. pricing too high-
