I’m having the same issue, would love an answer on this!

I am also getting this error, for a few weeks now actually.

I wanted to upgrade a couple of devices and initiate a trade-in, but it keeps giving me the same error for days now. Whether I use phones or laptops to try to make the purchase, it's not really an issue that seems to be happening on my end. I contacted support, but aside from processing the order over the phone, there didn't seem to be another solution. Unfortunately, the phone that I wanted (Pixel 8 pro) was showing backordered on the website, but out of stock on their end. So I wasn't able to do it over the phone either :/

Currently still having to deal with the same issue, have tried reloading the page and what not but getting stuck at the “add to cart” button

This might be due to the item not being in stock online currently.
