Waiting for the eventual clearance paid off! I found two 6" Black Series First Order TIE Fighters in the Target clearance aisle for $50.98 each. OMG were these boxes beat up! But I picked one up, and it was $55 and change after taxes.
Before I went to the store I ran a Brickseek search. Most stores in my area are still pricing the 6" TIE Fighter at $84.98, but stock levels are dwindling quickly at the $50.98 price point. And it came back with both prices and inventory amounts at specific stores. Only 3 out of the 20 stores that came back in my search had the lower price point, and those stores only had 1 - 3 units on hand.
While I know that there's likely to be another price reduction, I didn't want to miss out on this vehicle. And considering the condition of the box I actually cracked it open in the parking lot just to make sure it was okay, and sure enough it was.
