Where can I buy inexpensive throw pillows?

Decorative throw pillows are the single and most cost effective way to accessorize upholstered furniture, chairs at the foot and head of a dining table and beds.

I find the best, low cost decorative pillows at:

Pier One Imports
Home Goods
TJ Maxx
Marshall's

All at fairly reasonable prices. It is also worth your while to buy a bag of fiberfill to add stuffing to ready made pillows once the filling compresses after use. This will keep your pillows looking plump and new. Also, I always use Scotch Guard stain repellant on decorative pillows so they stay clean for a good long time.

While shopping for pillows, but several styles and colors, take them all home and see how they look. Keep your receipt and return the ones you do not keep. This saves time, energy and additional trips shopping.

Any discount store.

Check various stores in the clearance area, such as Ross, TJ Maxx, Marshall's, and Target. If you have a salvage store in your area, that is a really inexpensive place to find bargains. Too, they are VERY easy to sew with just a small amount of fabric, if you want to be creative.

Walmart,ebay,alibaba and other online selling platform you can buy a throw pillow,it is cheap and in good quality,more convenient than go to supermarket but you have to take care of the service and quality

Ikea

Try Walmart. Sometimes they have some Nice Ones- on Sale ! :)

Ross Stores, TJ Max, Marshall's have the best prices.
next would be Burlington Coat Factory and Big Lots.

If there is a Big Lots store around where you are check them. If they don't have any keep checking every week. Their stock is constantly changing. You can get stuff there as much as 80% off regular retail.
