Let's do some math. Let's say they have been out of stock since June. It's now December. Let's just say that out of the $175 list price, $100 of it are only parts and research, so they make $75 a piece. Let's just say there have been 1,000 SRI's sold since they've been on backorder (I honestly doubt that 1,000 MS3 owners bought SRI's, but just rounding up).
Example purposes:
SRI $175 ($75 profit).
Used SRI $175-$250 ($75 max profit potential)
1,000 sales x $75 profit margin ea. unit= $75,000 Gross Margin Dollars
1,000 sales x $175 POTENTIAL profit margin ea. unit= $175,000 (they could have brought in if they only sold it for $250 like most used SRI's).
I dunno. I'd say they lost a lot? Of course, these are only estimates if they make $75 a piece on them. I'd hope they do. Any less and that may not be worth it.
