bug with price limited coupon code in the cart?

[manch]

If i put the coupon code for example with minimal price limit 10000 and i bought something above this limit and i put the coupon code the it works fine ,but if i change my mind in the cart page and i cancel 1 book ,suddenly the price goes under the minimal price limit but the price limited coupon code discount still works!
