Honey voucher codes at Waitrose?

For months, I've been shopping online every week at Waitrose and using voucher codes found through my Honey plugin. For the last four weeks, I haven't found a single code Just wondering if anyone else is having the same problem? Wanted to check there wasn't a glitch with my Honey plugin. I had been saving £15-25 every week until they disappeared, so it's quite a big difference.
Before someone says it: I know there are cheaper supermarkets. 90% of my shopping is fruit and veg and Waitrose is the only place I can get it delivered and not have to throw half of it away because it's awful.
