Where is a good place(s) to get bras for good prices for teens??

I am 13. I need new bras and I need them to fit comfy. They need to be padded and underwired and a good price. My mom wont let me get Victoria Secret. She says they are too pricey for a still developing person.Where is a good place(s) to get bras for good prices for teens??
The last time I bought myself some bras I went to the Hanes outlet store at the Outlet Mall in the next town over from me. I use the Playtex 18 hour bras. I don't do well with underwire b/c it irritates my skin but some of the Playtex bras have underwire. For cup size on my Playtex bras I use a soft cup.
But as the other posters suggested you can find good bras at Wal-Mart but also check K-Mart, and Target or JC Penney and Sears.
Walmart.
jcpennys they give you a card were you can by them then you get one for free
WALMART! I bought Victorias Secret before and after washing them, they didn't last a month. It was a huge waist of money! You can find great bras at walmart for great prices, and they have the matching sets! :)
I only shop at Macy's or Belk they are reasonable , I have a daughter age 11 and that is where I took her , and I will never take her to victoria secrets for anything so ..yay mom
You can go to walmart and get cheap bras that are of good support and many nice designs.
