We recently just upgraded a website from Magento 1.7 to 188.8.131.52 and since then, we've been having a rounding-off issue with its prices. The website has some custom pricing modules installed. Here is an example:
Before adding it to the cart, the price is 1,332.05
But when it was already in the cart, the price rounds off to 1,332.10
I have been searching for a solution for 3 weeks now and still can't resolve the issue. If anyone can help, it would be highly appreciated.
Are you using PayPal checkout and/or Taxes setup. That might be related to that.
p.s. Please check that thread, http://magento.stackexchange.com/questions/829/what-is-the-status-of-rounding-issues-in-1-7
That might be related.
I don't think it's a Paypal or Tax issue since my tax applies on the Grand Total, not per product price
