Ordered 3,200 - got 2,500
I love these screws however... I ordered the 3,200 count of 2 1/2" screws. I received a box clearly labeled 2,500. That leaves me short on screws for the job ans raises the cost over 3 cents a screws which adds up. So heads up if you buy the bulk options, the quantities may not match.
Cost way to much!,
Would Not RecommendTo expensive for the amount of screws I got!
