Best Website for Cheap Las Vegas trip?

Although I have been to a dozen countries and at least 40 states in the US I have not been on a vacation in Las Vegas yet.
I have heard about tons of ways to save money on a week long trip there but I figured I would probe all of you for helpful advice from your personal experiences.
The trip will be late February and cover the Vegas Open weekend.
In fact when I was looking for extra GT's to go to I heard Jordan and Brandon talking about this one and suddenly remembered I have still never gone to Vegas on a vacation despite having planned trips to go there at least twice.
Any constructive ideas would be great!
Hell unconstructive ideas if they're funny are welcome too.
Happy turkey day all!

At first I thought this was a spam post.

Never go to Vegas longer then 3 days.

Was thinking 4-5 days because 2 will be largely spent playing Warhammer.

I was so in the middle of deleting this... Then realized if was a real post...

https://skiplagged.com/ may have some cheap flights.

Fly allegiant airlines. They are a newer airline in austin, Its non stop from austin to LV and its by far the cheapest. I fly them allot, yes they charge you for every little thing but all in all I spend less then 150$ round trip, sometimes cheaper.

Cool thank you, I'll check out both of those.
