It is the usual price, not a deal: $2.99 is in line with the typical price of $2.99 that DipScout measured over the last 14 days. It is the lowest in 20 days, but it has held this price since Nov 1, 2026.
$2.99
Today it costs $2.99 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $2.99 to $3.15. It's the lowest price in 20 days, but it has been at this value since Nov 1, 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 $6.23", but that is the store's own claim; we only state discounts our price history proves.
