Over at Amazon, this Martin 8-inch adjustable wrench is currently deeply discounted to just $2.92. It has a jaw capacity of 1-1/8″, and corrosion-resistant nickel-cobalt finish.
The product description says it’s made from drop forged American alloy steel, but with a seed of doubt in my mind I took a look at the sales flyer (PDF). Made in USA.

Right now the wrench is out of stock, with a shipping estimate of 1-4 months, but Amazon is still allowing for backorders.
Martin manufactures industrial and automotive tools, but these wrenches might be made for them by another OEM, such as Western Forge. Either way, they should be decent quality, and the price is hard to argue with.
The wrenches are eligible for free shipping on $35+ orders, or free shipping for Prime members.
