I worked with Shipstation support and they suggested I bring this up to the community. The add on is $150 per month and I asked Shipstation if there was a way to run a report from dates in the past to see if I would save more if I added the Rate Shopping app. It seems like a good idea, I sure do not want to pay $150 per month if it only saves me $100. I am sure the large shippers don't have this same issue as us but I am also sure some would like to know.

If you have your rate cards, i would export a set of data and upload that with your rate cards to ChatGPT and ask it to do a comparison of your data against the different rate cards and ask it to give you a report on saving potential.
