Dollar General
The places to purchase bedding comforters are many and varied. the best place to start would be Amazon. If you are on a tight budget, a good option will be eBay.
For affordable prices try Target, Kmart or Macys. they are the three leading discount stores that have more diverse bedding then Walmart, but equal prices to Walmart.

Ross For Less is a great place to find cheaper comforters, but also try Big Lots if you really want to bargain shop.
You can always go to Bed, Bath and Beyond for real down comforters, quilts and pillows.
Walmart is a great place for inexpensive comforters. Bed, Bath & Beyond is also a great place for anything involving the bedroom, and even Ebay has a great selection of inexpensive comforters - though you will have to be careful buying online; the shipping may end up more expensive than the item itself. Buy as close to local as possible.
