Then go to Walmart.

:

I haven't got one of these (I have no horse in the race) but just looking at the build quality, I think those are pretty decent prices, also US made. If you check against other cargo nets, prices are in line. Every cross over is box bartacked and the side straps too, that has to be sewn by hand (well with an industrial machine by hand), that stuff is well made.

There are others that are cheaper, certainly, you do get what you pay for.
