HELP!!!!

Okay, this might sound a little dramatic, but I'm needing some serious help here. I just spent a day, yes a day, (I told you I need help) looking for the perfect duvet cover for the "new look" I'm going for in my bedroom. I've looked at.....

Target
Macy's
Dillards
Kmart (yes you read that right, I'm desparate ok?)
Smith's marketplace
Bed, Bath and Beyond
JC Pennys
And I tried Linens and things, but they're out of business
and no, I'm not trying Walmart.

What other stores are there in Utah? Where do I look online? Those of you who have been to my house, you'll understand why I found nothing here. I need a pattern. I'm going with keeping the beige walls. I'm switching to all black furniture, black mirrors. The lamps are staying, white accents and keeping the black and white pictures of the family. I need a red based duvet cover with preferably white accents. Stripes, paisly, and some flowers ok. If you have any information on the whereabouts of such a duvet cover.....you know where to reach me. I can't do a dang thing about my window treatments until I get the bed figured out. Thanks!
