Quick answer
Is $6.40 a good price for MGN7 MGN12 MGN15 MGN9 L From 100-800mm Miniature Linear Rail Slide…?
It is the usual price, not a deal: $6.40 is in line with the typical price of $6.40 that DipScout measured over the last 14 days. It is the lowest in 18 days, but it has held this price since Nov 2, 2026.
The drop of Nov 4 (to $6.40) hasn't been re-checked in the last 48 hours. Check the price on AliExpress before buying.
$6.40
Today it costs $6.40 on AliExpress. Since Oct 23, 2026, when we started tracking it, it ranged from $6.40 to $7.70. It's the lowest price in 18 days, but it has been at this value since Nov 2, 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 $11.85", but that is the store's own claim; we only state discounts our price history proves.
