For self-employed if no offers shown online, then opening savings account is best way. If no branch nearby, you could try Selfie account opened online although it has debit card charges I think which initially will offset the 10%-15% offers on Amazon
Lately their debit card offers are Mastercard-only and they have cleverly changed all their savings accounts so there is no FYF Mastercard, but ₹300+GST=₹354 charges. This bank I feel is 2nd most greedy after Axis Bank (infamous for its consolidated charges).
