I am seeing a lot of concert options in the coming months but most of them are $120+, some are even close to $300! I am trying to find some cheaper concerts. In my home town, I usually go to them for around $50 so I am not trying to pay double or even triple to see a live concert.
Look for seats further back, some venues will charge you lower prices for seats higher up or further back. You can also look at various sites to find tickets on the cheap. Some people will sell via facebook, craigslist, and ticket resale sites.
Concerts in Vegas are usually pretty pricey.
You might have better luck checking out local bars, clubs, and other places. You will get cheaper entertainment this way. Of course, most of the bigger/popular bands/artists will cost you much more to see live usually.
Most concerts in Vegas are overpriced for the simple fact that they are in Vegas. Most of the time you can see the same show in a different location and often pay $100 less. I would skip concerts if you are looking to stick to a budget in Vegas.
