Throw my 3 cents on the table
I just built a 20 to 10 meter vertical and used the DX Engineering radial plate. ((Super product, btw)). I had never ordered anything from this company. I ordered the plate and several other items (( odds & ends connectors, z817 tuner, so forth)) on a Wednesday evening over the Internet, got a confirmation email right away, and the next morning an email that everything had been shipped and I got it all on Friday. Saturday morning I was laying down radials with the plate. Then I ordered a few more items the next Wednesday and same thing: I had it all on Friday. Great Service!! I would expect similar service if I called them on the phone? With Christmas coming up, I've already given my wish list to my kids and suggested $$ so I can get something else from DX.
I wish one of the other big name ham radio "companies" whom I shall not name had such good service.
