Buy a lot of snacks in Tmall supermarket, and pay for them one at a time, but are the packages of different snacks big boxes? Or a lot of boxes?

I have bought many things in Tmall Supermarket, but the quality is good and the logistics is not bad. What you buy on the first day usually arrives the next day. If there are many snacks, I will use two bags. Before, a box of bread and other snacks were two parcels, but they all arrived at the same time, which did not affect the receipt. The size of the box is not too big.
