Eh, sorry, what i meant is that we are selling items (snacks) for the price of $3.25 per 1/4lb or other weight . That means that she/he buy by weight. So we say he buys 3 of x item for 3.25 per 1/1/4lb.
But he can select by a drop down meny /weigts:
QTY: 1/1/4lb
QTY:1/2lb
QTY:3/4lb
QTY:1lb
Was it easier to understand me know?
