You might find one item, a radio or tuner that you want, cheaper at one place than another. But if you are
like me, you don't order just one item. Heck, you're paying shipping anyway, might as well fill the bill of
materials you need, right?
So, you need 6, 7 items, and some little stuff like PL-259's or whatever.
Add it all up, plus shipping.
Now check out the same order at any of the other places. One item might be more expensive, another cheaper,
but the whole order, all of the stuff you want, it ends up being within a few dollars of any of the others.
The shipping is the reason you don't order those six items from four different places.
In the end, I just look to see who has it all in stock and can ship now. And I've had good dealings with all of those
listed.
