LG has just dropped prices of some of their monitors and they look to be at ATL when you stack them with a $50 first-time member voucher. You need to sign up for a new LG account to get the $50 voucher which is valid for purchases above $350.
If you prefer a higher refresh rate (160 Ghz) then LG 34WP60C is also on sale for $399 which (even without a $50 coupon) seems to be all time low, however stacking with a $50 new user voucher - you can grab it for $349.
I have the 34WR50QC from the last deal, I'd recommend getting the higher refresh rate option if possible, especially when the price difference is so small. It really does help smooth things out a little.
