I'd check out the TAG forum at
Time Zone amd do a search to see if someone recommends a specific dealer.
I did this for an Omega and found a dealer whose standard "internet discount" was very close to what I could get it for from somewhere like Amazon. Still got all the advantages of buying from an authorized dealer which came in handy when I had to send it in for a repair.
TAGs are at least as common as Omegas. I'd be surprised if you couldn't find someone on TimeZone who could point you to an authorized dealer who'll get you close to an Amazon price.
