Given that RAM prices have skyrocketed over the past year, we are always on the lookout for a good deal. Relatively speaking, we found one—an 8GB (2x4GB) kit of Corsair's Vengeance LPX  (CMK8GX4M2B3000C15R) is on sale at Amazon and Newegg for $80.

Granted, this was a $50 kit at one point in time, though you have to back to 2016 for that price. The lowest it's been at Amazon this year is around $70, and that was at the beginning of January. More recently, it's been going for around $100, give or take.
