Hi everyone!
My sister and I are going to NYC.
We’re staying in Manhattan.
We plan on taking 5 trips on the subway.
Coney Island (to and from) = 2 trips
Hotel to Times Square = 1 trip
Times Square to Union Station = 1 trip
Union Station to hotel = 1 trip

I was gonna get an 2 OMNY cards and put $15 cash on each card.
Can I buy them at CVS/WALLGREENS/DUANE READE and load the money on at the store or should I use a machine in the subway station?

I really want to avoid using my credit card.
Any help is greatly appreciated.
Thanks!
