Be careful of Superbalist minimum spend deals

When placing an order for the first time (minimum spend R700) you get R250 off. Sounds great, but then suddenly one of the items is out of stock. They then cancel the item and refuse to refund you (because part if the discount was app**** to the cancelled item). If I had been the one to return an item, I'd understand that I would lose the discount, but since this is an error on their side I expect to be refunded. Especially since even without the cancelled item, I was still spending over R700! Seems like this is a new trick for them to use. I am definitely taking my online shopping elsewhere.
