The cheapest I was able to see is $115. You can order them on Amazon.com and they may provide free shipping for orders over $100. "accent benches" aren't that hard to find.
Accent benches are decorative benches for your garden or patio. They can be bought at any furniture, home improvement, or home decor store or even at general retail stores.
If you are on eBay.com and it says free then most likely it's free only to US. However there are some sellers that ship for free to some other countries (mostly Canada) You can find these information...
Free ground shipping is simply regular shipping that doesn't cost any money... It certainly is NOT rush shipping, though. If you don't care how fast the item comes, it's a good choice.
