TATA Card and Croma, Please guide me.

Hi guys!
I am back. Just wanted to know that after a shopping at a Croma outlet here in Faridabad, I was informed about the TATA Credit card that has great offers. My dad got the card. Now, the Croma guys told us that for every thousand rupees of shopping at Croma you get back 250 points. Now, as far as what they told me they said points are EQUAL TO Rupees. Is it true?
If I shop for 50000, does it mean I can shop for free with an amount 50X250= 12500?
Rs. 12500 of free shopping!:Shockked:
Atleast, this is what they made me think. I am figuring what all to buy. Whoa!! Help Help!!!! I am confused.
Anybody else who could help?please:
