I'm not making any big statement on the quality of Chinese products. That would be idiotic bearing in mind that the majority of products I use are made there or at least in the Far East. When it comes to Anchor Shackles, HOWEVER, I tend to err on the side of USA made products.
This is the one you find in most WM stores. A 7/16" will cost you $6.99 from WM. (photo is of a 3/8") CLICK HERE
This one is also stocked by WM but in most stores you have to order it from a distribution center. CLICK HERE. It takes a couple of days and can be shipped free (3-7 days) to your house. A 7/16" will cost you $17.99 from WM. I have found them for as low as $6.72 on the Interweb.
Maybe its just me, but anchor shackles are not a place I try and save money.
