Was browsing for a single monitor mount/arm and found this. Sold by 99% rated third party, fulfilled by Amazon. 3Cs says it’s been this price since May 10, but it has not yet been posted. Previous $20~ deals have been pretty popular here and no coupon is needed for this one.
Recommend against $130 professional installation, but treat yo’ self if you feel the need
