Exclusively for Prime members, Amazon offers the Patriot Viper Elite Series 16GB PC4-25600 DDR4-3200 288-Pin Desktop Memory Kit with two 8GB DIMMs for $94.99 with free shipping. That's the lowest price we could find by $60 and a particularly noteworthy deal, given the current RAM shortage. It features a 3,200MHz clock speed and 16-16-16-36 timings.

Note: It usually ships within one to four weeks.
