Buy Together Calculation Wrong

I created two products:

  1. INTEL - $150
  2. Motherboard - $75

    Total Amount - $225

    But when i click Add All To Cart Button, i see the total amount on view cart page showing wrong, it is $215 instead of $225. Please help.

    Edit - I just checked not only in buy together, my whole products showing wrong price when i click Add to cart button. Please help

Then you probably have an active cart promotion that is reducing the price.

I disable all promotion but still showing incorrect price.

Then you have some debugging to do.

Check for group pricing, promotions, quantity discounts, etc.

I've not seen what you describe so it is probably something with your particular setup.

I found the problem. You can check this thread which i opened last tiem about bulk price change.
