rate tart - definition and synonyms

noun
  1.   From our crowdsourced Open Dictionary
    someone who regularly switches credit card providers or savings accounts in order to get the best interest rates available

    With Bank of England interest rates stuck at 0.5 per cent and UK savers subsidising borrowers to the tune of an estimated £100bn even the most active of consumers, those willing to become a "rate tart" and switch between the highest-paying providers, are barely keeping up with inflation.
