We have a 6' bed and I buy all my linen in Florida including pillows. I used to buy it in Burdines in the Florida Mall but when it changed over to Macey's the bedding department seemed to shrink in size and the selection suffered as a result.
I now look in Beds Bath and Beyond for pillows and Ross Dress for Less for sheet sets and comforter covers. They did have King size covers but not twin size which I was looking for on my last visit.
Why not look in Beds Bath and Beyond for "Bed in a Bag" sets, you get comforter, shams,sheet sets and valance ranging in price from $80 to $200. Some sets I looked at in April this year came with 2 sets of sheet sets and extra pillows to dress the bed.
Ross also has Bed in a Bag sets and comforter sets but don't normally have as big a selection as Beds Bath & Beyond.
If buying a Bed in a Bag you should also buy a Jumbo space bag to get it home. In the Flea Markets on the 192 they sell extra large holdalls ideal for taking home clothes and bedding which have been packed in space bags.
Best place to buy space bags is Walmart and you'll find them in the aisle with Vacumn cleaners in.
