I have 95 items listed in the same category and all have the same volume pricing promotion. Only one item has developed a glitch where my customers can only add up to three items to their cart even though there are 75 items in stock. If the customer adds 4 or more, they get a 'The item you've selected was not added to your cart.' message. When they add three or less, the items are added to the cart however, it they try to increase the number to 4 or more in the cart, they get 'Item(s) in your cart are not available in the quantity you originally requested. We have updated your shopping cart to reflect the amount that is currently available. Please review these changes before proceeding to checkout.' Again, there are 75 items in stock so there is some type of glitch on this one item. Can anyone help correct this glitch?
