Sprite — Mrp higher at r city mall

Address:

400059

I purchased a bottle of thumps up and sprite at r city mall, ghatkopar two days ago. While price of thumps up was rs. 38, price of sprite was rs. 60... Both were printed prices hence did not argue with the counter staff as i thought maybe that was the actual selling price all over. Yesterday at dmart, chandivali when i checked the price of sprite i was shocked to see it at rs. 38!! Why two different prices at two different places for same product??
