Why bother with which? I don't understand the question.

Delivery is for less frequent things that last much longer.

Local ships are for more frequent things that spoil quickly.

And adding the heavier/bulkier things to my local trips, even in smaller quantities, just makes the bags too heavy and unwieldy in the end. I only have two hands. Plus it's way more expensive to buy paper towels as individual rolls than in packs of six.
