This is my favorite savers in the Las Vegas area. We went to visit 2 other ones and found this one to have the best variety. The store was clean and didn't have the muggy smell you sometimes experience with thrift stores.
We went on the 50% off day sale. They do these a few times a year and usually on holidays. If you have the club member card, you can go a few days prior and shop before the public does. Card is free, just ask one of the salesperson to sign you up.
I think everything is worth it during the 50% sale. However, when it's just a normal day, you really have to dig because you can sometimes find the same deals at Ross. I find thrift stores to be fun when you have the time and everything is organized and Savers does just that.
