Some update from the poster.
I contacted eBay today, some listing 'specialist' took a look, and then she told me volume discount is working when she checks out and asked me to check my cart. I totally don't understand why 'my cart' would do anything with this and I guess she referred to her cart., but why she doesn't understand that I couldn't see her cart? Even if that worked, what's the point of not knowing there's a volume discount until buyers check out? Before it stopped working, banners can be seen on the listings and prices change right after quantity is changed.
She also told me it could be because I updated prices in the past 7 days, but unfortunately she couldn't get it working after she tried on a listing that hasn't been updated for a while. Then she told me because there's some insurance I offered might cause the problem. **bleep**? The insurance is from eBay not what I offered, eBay just 'hijack' these listings to ask buyers whether they need 3rd party insurances, why does that have anything to do with the seller? And realistically, even if there was a price change, why would that affect volume discount? As a seller, I would still like to encourage buyers to buy more no matter how prices are. Do these eBay programmers ever understand market?
