Are Tanishq digital gold prices higher than Malabar or Kalyan Jewellers?

I’ve been comparing digital gold prices across different jewellers and noticed Tanishq sometimes looks more expensive than Malabar or Kalyan. Has anyone done a proper comparison? Are the prices really higher at Tanishq, or does it balance out with making charges, purity, or offers? Trying to invest for my mother. would love some help
