match email addresses across two sheets and return value from one sheet to the other

I'm sure this is easy...but not quite getting it!
I have two sheets in a file. 'attendees' and 'products'

Attendees:
Name/Email (all attendees)

Product:
Name/email/parking/evening (only those attendees who bought parking or evening tickets : parking and evening is a number of tickets)

the product sheet is a list of those who bought parking and evening tickets.

I want to add two new columns to 'attendees' that will show their parking and evening tickets having looked it in the product sheet.

thanks!
