You want to get your mom her favorite perfume, Si by Giorgio Armani. Since you came to Macy's early you have the option of buying her just the perfume or the set that also comes with lotions and stuff. Option #2 is obviously more expensive, but she may like it.

1. Buy her just the perfume and save some money for yourself for the rest of the day.
2. Buy her the full gift set and have less money for yourself.
