Don’t just ask for a spark plug, insist on NGK.

NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using a laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.

Worth ordering
This seems like you get more at once than buying from the eufy store and I use it pretty frequently with 2 dogs and a son in the house. This keeps me from having to order so often.
