You should check the account you're logged in as. It probably doesn't belong to the correct customer group or company in your eCommerce environment.

WooCommerce Pinpoint Booking system not showing prices correctly

I'm Pinpoint booking system for reservations and WooCommerce for payment. And I see the following problem:
The system is supposed to calculate prices based on number of selected days for the booking, but, when selecting multiple days for a booking site, in the WooCommerce cart the amount reflected in the woocommerce screen is not what is reflected in the booking pinpoint piece (the booking Pinpoint piece is calculating correclty the amount based on qty of days, but the WooCommerce section shows the price for only 1 item).
For example, if I book for 2 nights at $8/night, the check in/check out part of the cart shows $16, but the Woocommerce part of the cart page shows QTY 1 at $8 (being the product price for a single product).
How do I fix this?

Paypal shopping cart contents not showing on Transaction details page since Paypal site upgrade

PayPal made some changes to their site this week and since then the contents of the shopping cart are no longer showing on the Transaction details page, nor in the csv activity download. This issue applies to older transactions too - ones that were working before the site changes.
For info, the shopping cart details do still appear on the confirmation email sent by Paypal.
Does anyone know what might be causing this?

PayPal buy now / shopping cart with and without postage assistance

I am looking for assistance with multiple buttons on a page, some which have postage and nultiple items, some without or free postage.
At present i have a standard shopping cart option on a page created from the standard create button PayPal page, which provides a space for the buyer to type in their requirements with includes free postage and works fine.
A second shopping cart on the same page offers a similar buyer feature but adds postage, all works fine.
Third, fourth and fifth buying options are single buy now buttons each with added postage.
But the problem for the buyer is that when they a add a single item with postage and a multi-buy shopping cart option, they end up with duplicate postage...
If they buy 2 single items using the buy now buttons + a multi-buy they end up having three duplicate postage costs in their order.
Any suggestions welcomed to avoid duplication of postage costs, thanks.
I'm not sure how you currently have the shipping set up (whether via the buttons themselves or the shipping profile), but this is how I would tackle this:
For the items that are free shipping, within the shipping option in the button itself I would set a shipping cost of 0.00. Then set up the shipping calculations section in Tools or your Profile for your shipping rates for the items that do have shipping costs. In the last step of the shipping calculations creation, you want the box to be checked to use the shipping cost in the transaction instead of your calculator settings and that will allow the buttons you have a shipping cost entered directly into to override the shipping costs you set in the shipping calculator.
If you need any assistance setting up the shipping calculator you may call into PayPal Support and they can assist you.

Discount with PayPal REST API

When submitting a payment via PayPal's REST API a collection of Items must be provided where the price * quantity = total.
The following screen grab from Fiddler illustrates my problem:
The value for the "price" element must be in the format "0.00". However, in the case above I started with a price for loose photos of "£0.08" then added 20% VAT to give "£0.096". 300 * £0.096 is £28.80, so the total cost of the order is given correctly. Problem is, I have no way to present the unit cost to PayPal. Could anyone please advise how to solve this problem?
I had similar issues with shipping options and chose to write my own shopping cart code which displays individual items selected plus tax and shipping options. A 'pay using PayPal' button on the form simply submits the total price to PayPal. This gives me total flexibility - I recently switched to free shipping on orders over $x. Also the shopping cart is much faster and responsive than using Paypal for every item selected - so I get more orders going through to completion - always a good thing!
