$0.49
Today it costs $0.49 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $0.49 to $0.60. It's the lowest price in 23 days, but it has been at this value since Nov 3, 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 $0.71", but that is the store's own claim; we only state discounts our price history proves.
