So, Lex introduced me to Gottscheer Hall, which is an essential place. The cost of shopping at places like NY Bakery Inc, Netcost, and evidently Moschers is still hilarious. As a regular non-car schlepper, I always take one of the many insulated/cooler bags I’ve picked up as random freebies over the years, like pens and pencils. I imagine they can be purchased too.
I've got a soft-sided Coleman cooler bag which works really well. Fits perfectly in the back seat too.
