Body lotion reccomendations for my girlfriend's birthday?

It is my girlfriend's birthday in a few weeks. Over the past few months, I have heard her say in passing that she really wants a nice body lotion (sometimes has mentioned grapefruit-esque scents). I know nothing about lotion but want to get one that feels luxurious and nice for her. If anyone has any recommendations for lotions that would work as a present, please let me know. Price range is maybe around $50? Maybe more? I am not sure what is standard here.
