Quick answer
Is $18.55 a good price for Prolific USB Type A USB-C to DB9 Male RS232 Serial Converter Adapter…?
It is the usual price, not a deal: $18.55 is in line with the typical price of $18.59 that DipScout measured over the last 14 days. It is the lowest in 19 days, but it has held this price since Nov 5, 2026.
$18.55
Today it costs $18.55 on AliExpress. Since Oct 23, 2026, when we started tracking it, it ranged from $18.55 to $19.25. It's the lowest price in 19 days, but it has been at this value since Nov 5, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 14 days. The store advertises "was $19.20", but that is the store's own claim; we only state discounts our price history proves.
