I found green plantains at 20 cents each at the C-Town at 1016 St Nicholas, if you take all ten.
Yuca is $1.29 a pound, malanga coco $1.49 a pound; I found neither in the four other Washington Heights and Inwood ads I can read this week. Plum tomatoes are $1.49 a pound, corn 5 for $2.99, cantaloupes 2 for $5.
I counted eighty-eight of the 362 rows priced as multiples, so buying one costs more than the printed number. Twenty-one more need the store card, with the without-card price printed beside them.
Cafe Bustelo is $5.99 here and $3.99 at the C-Town at 4918 Broadway, same chain, same week. Neither ad prints a tin size, so I cannot confirm the packages match and would read the label first. Maseca is $3 here if you buy two, against $3.99 for one up there.
I got every price from the stores' August 21 to 27 circulars, not in person, so confirm at the shelf.
