My guess is it depends on the particular speaker. I was able to get 50% of the MSRP on my 803s when purchasing 802d3, but I originally purchased the 803s from another vendor (that wasn't interested in trading). I later was able to get 50% of 805's (d2) in trade for 805 d3 (I could have gotten more other ways but with more hassle on my part), but they weren't interested in trading in my htm2 d2 for an htm1 d3, which I later sold online. But none of these speakers that I traded n were originally bought from Magnolia, so YMMV. I will definitely say that Magnolia have been very willing to help me find ways to upgrade with them
