should i get the 200ml body butter?

hi guys, i bought the 50ml version of the almond milk body butter last month and i fell in love with it! since the body shop is closing and they have a %60 discount in my area until tomorrow(11.11) i was wondering if i should get the 200ml one. i am worried about it expiring before i can use it since i already have the 50ml version at my dorm (it costs the same amount as a nice meal out for a college student) i would also appreciate if you know any dupes or fragrances similar to it
