Disclosure: this is my own site, so flagging that up front. Posting it here rather than in deals because it's a free tool rather than a one-off bargain.
I got sick of having ten roaster tabs open trying to work out what was actually good value, so I built coffeeaddict.nz. It reads the published prices of 152 NZ roasters every night, 2,862 bags at the moment, and puts them all on one page priced per 100g. Means a 200g bag and a 1kg sack finally compare properly.
It also tracks price drops, new arrivals, and each roaster's shipping terms, which matter more than you'd expect. A $10 bag with $12 freight isn't a $10 bag. Subscriptions too, and some of those work out dearer than just buying the beans.
No ads, no affiliate links on beans, nothing sponsored. Roasters can't pay to rank, so the cheap bag at the top is just the cheap bag.
If your roaster isn't on there, let me know and I'll add them.

This is great, thank you! I've been wanting to try out a few more local roasters but a lot of effort to trawl through all their websites for per kg pricing. Just tried that location based search and gave me a few hits of places I've not tried of before.
