Al derech what it says in OC Siman 323 that one shouldn’t bring cadei yain through the reshus harabim unless he makes some sort of shinui in the way he does it, what would be the din in regards to bringing many boxes of mezonos for a Kiddush from someone’s home to the shul?
Answer:
Perhaps.
The Shulchan Aruch makes special mention of bringing jugs of wine in a basket and box, and perhaps this was a special uvdin de-chol that will not apply here.
Either way, the Shulchan Aruch himself writes a second opinion, which maintains that it’s better to carry them in the least strenuous manner, so that it seems best to just bring them in in the easiest way possible.
Best wishes.
