Quick answer
Is $2.39 a good price for 50pcs LM393 LM393DR LM393D SOP-8 Comparators Dual Differential new…?
It is the usual price, not a deal: $2.39 is in line with the typical price of $2.43 that DipScout measured over the last 14 days. It is the lowest in 18 days, but it has held this price since Nov 5, 2026.
$2.39
Today it costs $2.39 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $2.39 to $2.44. It's the lowest price in 18 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 $6.83", but that is the store's own claim; we only state discounts our price history proves.
