Price on Shopping Cart & Price on Paypal Differ

Hi gandeming what are your settings on the admin? What shortcode are you using?

Thank you for the speedy reply.

These are the codes I use:
[wp_cart_button name=”6 Days Proofread” price=”0.036″]
[show_wp_shopping_cart]

Here are my settings:

Thanks again

Hi can you Enable Debug and Enable Sandbox Testing. Check the log files and report back.

Also your currency RM is not listed in PayPal, see the following link.

Thank you

I have enabled it. I have also created a sandbox account on Paypal. But when I click on the file ‘ipn_handle_debug.log’, it opens up a blank screen. RM is the symbol for MYR (Malaysian Ringgit) which is listed in the link you provided. Even when I changed the currency to USD, the mismatch is still present.

Thank you!

Hi try and use MYR instead of RM.

Let me know how you go.

Thank you

Done that earlier. Same.

Hi, in regards to setting up an IPN please click on the following URL.

Thank you

Okay. Done that but it still is empty. What do you suspect to be the problem mbrsolution?

What type of PayPal account do you have?

I updated my account to a business account.

Hi gandeming, did you just update your account to a business account? If you did have you carried out some test?

Regards

I think I know what the problem is.

The price of my product are written in 3 decimal places as a single unit of the product costs 0.036. The number displayed on the Shopping Cart is the rounded number = 0.04. However, in doing the calculation for the total, it takes the original cost (0.036) and multiplies it by the quantity (0.036 x 250 = 9). Therefore total in shopping cart is RM 9.

However, Paypal uses it’s own calculation. Instead of obtaining the total of RM 9 from the Shopping Cart, I think it obtains the value of a single unit of the product (rounded off, so 0.04) and multiplies it by the quantity (250). Which results in it costing RM 10.

Due to the difference in calculation, we get different values.

Question: Is it possible to edit the plugin so that Paypal acquires the total displayed on the Shopping Cart rather then letting Paypal calculate on its own?

Hi gandeming it makes sense what you are saying. In regards to this question one of the plugin developers will investigate this further for you.

Kind regards

That would be fantastic. Thank you so much.

PayPal only supports pricing upto 2 decimal places. So you will need to adjust your pricing unfortunately.
