ivolatility data Black Friday sale

Hey all,

If anyone is into analyzing options data/strategies in code I just wanted to point out that ivolatility.com has a 30% off sale on their data. I picked up SPX on sale last year. I had a group when I purchased and they let us share the purchase across 5 people.

Anyway, just a heads up.
Be careful though. I bought SPX historical intra day data from them and realized that they are missing the corresponding SPX price and some greeks before 2014. It's not a bug but they confirmed they don't have the data.
