Where can i find reasonably priced quilts or duvet covers for my bed?

sue.sister asked:


I need a cute quilt or something for my bed, in the colors of yellow, blue, and green. (my room’s yellow) Where can I find one to buy? What are stores or maybe catalogs that aren’t too expensive (like pottery barn is!). I was imagining stripes and/or polka dots. Any suggestions? I’ve looked at domestications.
