Target has the 75425S on "sale" for $899.99.
Best Buy has it on sale for $699.99 (reg price of $899.99).
I went to Target today hoping for a price match to BB and then getting the extra 15% off today only (11/24) that they advertised in their ad for TVs and soundbars.
Because Best Buy's sale price was a normal sale and not a clearance or Black Friday only price Target price matched it and gave me the 15% off so the tv cost me $595 + tax ($648 here in MO).
Since I can't guarantee you that it will work at all Targets I put YMMV. If I haven't posted this correctly just let me know and I'll try to fix it.
I used my Discover card as I get 5% back from Target this month. I don't have the Target card, and unsure of their exact policy, but I thought I read that it gives 5% back at Target.
I used the calibration settings on rtings on my 55" 4 series as well as this and am personally happy with the results. This is the link to those settings if you want to try them out.
If you're on the fence about the TV the $699.99 Best Buy deal got 70 thumbs up so even at that price many people thought it was a good budget big screen TV.
