Shops/websites ?? Where to buy sarees in US ??

Hi all,
My mom has come to stay with us for helping with my delivery.. I know that she wants to purchase some US manufactured sarees as gifts when she goes back ( I believe she received them as gift once before and some of them are extremely lightweight and nice to wear). Honestly, this is how I came to know that we can even buy sarees in US !!!!
So, now I got a nice idea - I am thinking of buying a saree as a surprize gift for my mom for wearing on punyajanam day ( 11th day after birth of baby).. I want to know how/where we can purchase saree in US..
We stay in Phoenix Arizona. We dont have too many great Indian shops here, and I am guessing closest brick and mortar shops would be LA ? SFO ? Could anyone help me with some shop names where you bought sarees ( either Arizona or California??)
Also, if you know any website or online store where we can purchase sarees, that would also be very helpful..
Thanks a lot, in advance..

Love
Savitha
