Prices vary, naturally, but we saw prices range from about $160 to $220 or so during the October Prime Day sale on Thunderbolt docks. We'd hope for more of the same. In 2023, you benefit from one key trend: Thunderbolt 3 and Thunderbolt 4 are roughly the same in terms of throughput and features. But retailers hate keeping old hardware on the shelves. It's likely that you'll still see substantial sales on older Thunderbolt 3 hardware, with lesser discounts applied to Thunderbolt 4 docking stations.
