If you have a Fry's Electronics near you check their CB radio section (that is IF a store in your area carries them) I don't know for a fact but I suspect they may be clearing out their radio merchandise. I posted picture of mine that was purchased for 223. new. Amazing find. I could not rationalize forking out 500 dollars for a toy in the house only I would use, so the low price made my decision. FYI about that Radio Shack deal- the consensus is it may be "legit" as OP posted pictures (as I did also, with the price sticker and my receipt)
this is all speculation but maybe just maybe Uniden is telling retailers to "name their own price" to liquidate all old product on shelves? Considering the low low prices we are hearing about.
