It's a Serissa foetida,
It's not going to survive temps below 50f, Here is a care sheet:
A quick aside: Strange that you would buy from NYC when right in Rochester [Well it is actually in West Henrietta ] is the International Bonsai Arboretum run by world renown Bonsai artist, Teacher, and Publisher [International Bonsai] William N.Valavanis.
There are also a few high quality bonsai nurseries in your local area, Something to consider for the future.
