*%*#!* ROCKAUTO SHIPPING ALGORITHM ?!!*!?!

I click on an item, I add or aubtract an item, suddenly the previous items I have sorted change their shipping location origin.

Has anyone figured it out?

It’s like playing chess with a cheater where you have to turn your back from the board and all the pieces have been moved.

Add or remove one thing right before your ready to sign off on the purchase and it all goes to ****!!

This is a great test of patience and I am failing at it.

I need help selecting items in rockauto and keeping the selected items origin point of shipping from changing.
