Basket of Many Things for mtgbasket.co.nz by Jack Gorman

mtgbasket.co.nz finds you the cheapest way to buy a Magic: The Gathering deck across New Zealand stores. This is its companion extension: it does the parts of that job that have to happen in your own browser, because a website can't do them for you.

Filling your cart. Most stores use Shopify, so the basket loads with one link. Three stores (HobbyMaster, HobbyLords and FetchTCG) don't, so adding a full basket meant doing it card by card. Click "Add all" on the basket, and the extension opens the store and adds every card to your cart for you, using your own store session. Nothing is added without your click.

Importing from Moxfield. Moxfield blocks websites from reading decks for their visitors, so mtgbasket.co.nz can't import one on its own. The extension can, because it runs in your browser, where Moxfield answers normally. Turn it on and you can paste a Moxfield deck link, or bring in every public deck on an account. It opens Moxfield in a background tab, reads the decks you asked for, hands them to mtgbasket.co.nz, and closes the tab. It never uses your Moxfield sign-in, so it can only ever read decks that are already public.

Moxfield access is off until you switch it on in the extension's options, and switching it off removes the permission again. The only thing this extension ever sends anywhere is a deck list you asked it to import, and it goes to mtgbasket.co.nz to become your deck. No account, no analytics, no browsing history.
