$0.58
Today it costs $0.58 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $0.58 to $0.59. It's the lowest price in 7 days, but it has been at this value since Oct 30, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 7 days. The store advertises "was $1.50", but that is the store's own claim; we only state discounts our price history proves.
