Is acbuy spreadsheet worth it? 78 day review

Quick question for the community - I'm trying to use acbuy's spreadsheet feature but running into some issues. I've followed the guides I found but something isn't clicking. Specifically, I'm trying to order phone cases and the process seems different from what others have described. Has anyone else encountered this? The interface looks different from the screenshots I've seen. I've already tried clearing my cache and using a different browser. Same result. Any suggestions would be really appreciated. I've been stuck on this for 45 hours now. Thanks in advance!
