I dunno how many sossies you buy at a time, but with our gluten-free requirements we sometimes go to specialists, which makes a slightly larger order more sensible.
The box was 24x13x10 inches.
Take 1" off both width and length for packing, 2" or a little under off the height for packing and chillbags.
That still leaves around 2200 cubic inches of space for sossies - though some of it's taken up by the bonus burgers...
I think we can say we're sorted for sossige, for some time to come.
OTOH, I promised the butcher in Tod Market I'd buy some off him tomorrow.
