If you go to Brit's show - you have to check out the store! I was a little disappointed that there weren't more items available, but I was pleased with the quality of items they were selling (albeit, they were pretty pricey).
I purchased the black/gold glitter "Work Bitch" mug for a co-worker ($20), gold travel "It's Vegas Bitch" mug for myself ($20) and a black and gold glitter muscle tee ($40). I got a free iPhone "Work Bitch" case with my purchase....which is exactly what I DON'T need since I don't even own an iPhone - however, it was a nice thought I guess.
The employees in the store were really sweet and helpful. I went to a show after Britney had been on break for awhile and the worker was commenting about how many shows she was doing a week and how dedicated she was. I'm not sure if he knew her personally, but it was cute to hear someone talking about her so positively.
