This has been asked countless times here. I've never heard of such a sale with regards to the SDS series scanners, Uniden's prices are pretty much set in stone. Every so often, retailers like HRO might knock off $50 or so on a x36hp or 325/996p2 and if you're lucky you MAY find a second-hand SDS200 in good condition on the classifieds section here typically for $50 or so less than MSRP but they sell faster than hot cakes so you gotta act fast
You would think so but I don't think I've ever seen Uniden do a Black Friday deal or really any deal. I've seen some of the scanners, like the BC125AT, go on sale and drop down to about $89. But I've never seen any sale on the higher end products until a new top of the line product comes out. Especially on their latest radios in the SDS series even though it's two years old now for the SDS100. I wish they did have deals because I might be inclined to buy another SDS200.
I could be wrong, and maybe they do sometimes have deals, but I don't think I am and I have never seen one before If they have had sales on the top tier products.
Few weeks ago a reseller on Amazon knocked down the price of the SDS200 for a day or two. Was a big thread on it. Otherwise, basically what the others said above - don’t expect to see much on a deal from them.
About a year ago, Amazon had the BC125AT on sale briefly for $85 so I snagged one. I already had a BC125AT but at that price I couldn't pass it up. Since the pandemic, though, it hasn't dropped below $110. And the SDS series? It will be a few more years before we see any substantial savings on those units. So, suck it up and pay the going rate unless you want to wait until 2024.
