Problem with ebay multi-buy discount?

LM2020

I've noticed a buyer has been charged full price for an order for several items (from the same listing) when they should have had 30% off. It is showing all as one order so they didn't checkout each item separately and the offer was applied correctly to a different order earlier today. Has anyone else had an issue with this multi-buy discount not being applied or know why it might not be working?

Probably just a glitch.  It happened to a buyer of mine once a couple of months ago but hasn't happened since.

First simple check is to see if the promotion is still active in the promotions tab on seller hub.

Does the offer work with the BIN button? If not they might have used this rather than the basket? 

Is this across multiple items? If so do you have it set to allow multi-buy this way (I think you have to turn on the option for multi-buy to work across listings?

Are all the listings they purchased from grouped under the same promotion? 

I assume it's multi-buy and not order discount?

Thank you for your replies. Yes - was wondering if it might just be a one off glitch. It's a multi buy all from the same listing. The promotion is still active and worked as normal on a multi-buy order earlier in the same day. The buyer must have paid all in one as it's come through as a single order and one total amount in my managed payment section. Unless they clicked BIN and "commit to buy" on each one? - I've noticed a different "commit to buy" page when I've clicked BIN from a managed payment seller so perhaps this stopped the discount being applied.
