Had no problem whatsoever. In and out of Target today in 30 seconds with my price adjustment on the 37" Olevia TV (which my parents love - great picture).
Walked up to the counter, gave the girl my receipt, she nodded (as if she had been doing a few times, lol) and said, "You got the Olevia 37 and want the price adjustment to $549 right?" She scanned the receipt, pushed a couple of buttons - voila. But as you can read my post in the Olevia 37" thread, it depends on the Target. The High Point, NC Target was horrible. The Kernersville Target - a breeze. I opened a Target credit account and had gotten 10% off too - I got to keep the 10% off for the price adjustment too :) - so I got the TV for $500.
The original Target I went to on Wednesday (High Point) had given me a hard time. I even had to listen to a lecture no how "well, sir, even if we did price adjustments like that, it is not fair to all the people who stand in line on Black Friday to get the TV. It is first come first serve and why would they even have a Black Friday sale if they would allow customers to do that". Again, just seethed with animosity and attitude from the manager. I was nice, but I did tell him that I while I kind of agreed with the whole "not fair for people who wait in line" that it's not my fault that Target allows this policy. If they allow it, why not take advantage of NOT having to stand in line. But it doesn't matter now, I got my TV and my adjustment and I'm happy.
Overall a pleasant experience with that particular Target, but I do wonder if they will continue to do this policy for the years to come.
