Is there a discount available for purchasing the Turkcell Annual Happy Mega 70 GB Package?

[Alfo]

Hello, I'm considering getting the Turkcell annual package and wondering if I can apply a discount on the price of 320TL. Would there be a discount if I make the payment through banks like Tosla, *******, Papara, Pep Vs.? Can anyone provide information on this?
