Ypsilantian J. H. Wortley's 1913 Grocery Tab: The Final Week

And here is the end of J. H. Wortley's tab for January, 1913--paid in full.

Surprise, surprise: canned goods existed in 1913, which DD did not know: there's a can of rather pricey peas, and "2 corn (25 cents); 3 peas (50 cents)" a few days later, which also suggest canned goods.
Finally, a bit of cash and a new broom, for 50 cents, to sweep away this tab, leaving many questions, including:

Why in the Sam Hill did this individual/family purchase 24 units of celery in January, 1913?!
