Add to cart is broken

Some items cant be added to your cart and that is really frustrating because I dont want to have to make 7 different purchases because I want 7 different items. And If Im looking for a specific item even after I search for it I have to sift through other items that dont really have to do with what Im looking for. Also even if I put in to look at items prices lowest first the prices are still mixed.
