$1.98
Today it costs $1.98 on AliExpress. Since Oct 24, 2026, when we started tracking it, it ranged from $1.98 to $2.03. It's the lowest price in 3 days, but it has been at this value since Oct 26, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 3 days. The store advertises "was $4.22", but that is the store's own claim; we only state discounts our price history proves.
