Scamming on Purim. That's just low!

While writing the previous post I received an intriguing call.
A female voice, calling me by my full name, asked if I have ever purchased from their store, pronouncing store`s name so fast I could barely understand it.
She then continued telling me that I have been marked in their lists as a VIP customer and eligible for a prize of my choice: silver necklace, exclusive leather purse, or juice squeezer. Yes that's right - a juice squeezer.
Which could be mine only for a small delivery fee of 39.90₪.
Needless to say our conversation ended there.

I guess we will never know whether it was "buy a 5₪ necklace for 40₪" scam or just an attempt to steal someone`s credit card info. But doing this on Purim? Where is the ethics!!!!
