I'm having problem with the Coupons Minimum amount. i set it to minimum of two products as what the description says.
Minimum amount This field allows you to set the minimum subtotal needed to use the coupon.
But when i made a test purchase i only purchased one products but yet the coupon is successfully added on my cart.
