wholesale price, only one product with different quantities from the others

[claudio06]

Hi,

I am building a shop for a client with 50 items. All the products are sold by the amount of 3, 12 or 24. I managed to alter the code to get these figures, and everything goes ok on updating the cart! However, there is one unique item that my client want to sell under 5, 15 and 35 quantities. Is there anywhere I can alter the amount for an specific item only? I tried to create a group for this product but the shopping cart does not update the price correctly...
