I have searched the forums to see if this issue was recognized by anyone else in the past or past versions of Ablecommerce. We recently have tested on both non and production websites and we have found when one product is added to basket the shipping estimator is correct in cost based on our UPS negotiated rates. (Ablecommerce latest version.)

When you add another item to the same basket and check the estimator for shipping cost the cost of total shipping for 2 items decrease's in cost. We now end up paying the additional cost that should have been added and not subtracted for the total shipment when adding multiple items to the basket.

I have not looked at the code to dive into this. However, if anyone else has had this problem please post.

Thanks again for any feedback on this.

Hi, I believe what you are observing is a limitation of physical reality.

When you have one item in the cart, AC can send the dimensions of the item AND weight to USPS for an extremely accurate estimate.

When you have more than one item in the cart, AC has not way of knowing the actual dimensions of the box with said items in it. All it knows is the weight. As such, only the weight is passed to USPS.

Depending on what the first item was, this could lead to extremely inaccurate shipping estimates with more than one item.

I'm not aware of any way around this, short of adding an additional charge to your shipping estimates.

Regards,
Charles

Hello, thanks for your input.

I would like to hear from the (Able Team) on their thoughts to this issue. We have not seen this before. I know that AC7 and even back to the old Cold Fusion platform this was never a problem. Please note: that this is only being seen with UPS on our websites and not USPS.

Also, we don't have this issue with other .NET platform we test against. Our goal is not having to babysit our shipping cost by manually adding or subtracting cost for UPS shipments. Don't have the time for it!

If ups can send us a bill because a package weight or dimensional weight were incorrect when we create the shipping label, I would think that Ablecommerce should see why this calculation is not working correctly with AC9 using the OAuth plugin and what is being sent to OAuth in order to calculate some type of correct charges.

If this was a free and open source platform we would customize this process, but it is not.

Thanks again for your input.

Ricky
