I went through a bag and like it. The larger briquettes seem to hold together well and the weather resistant re-sealable bag is a nice touch especially for those of us in wet climates. If you like using briquettes and experimenting with different fuels I would recommend trying a bag.
Personally I think Kingsford is garbage even at 1/2 price. It's like tear gas if you get a waft in your eyes, but I'm supposed to use it to cook the food I'm about to ingest? No thanks. Fine in a pinch but def not as a go-to for me at least. RO briquettes are a substantial improvement over Kingsford but not quite as "premium" as the Weber...
That being said at 2-for-1 RO vs Reg price Weber I would grab the Royal Oak deal.... Actually that's a lie... I'd just grab some lump
