All friends and DA members got 25 galleon certificates to the following: Honeydukes and Weasley's Wizarding Wheezes. The Weasleys (aka the Twins, Ron, and Ginny) received 50 to Honeydukes. Plus the following:
Dean - Gryffindor tie clip plus the other half of the FIFA World Cup tickets his father got for him. Note attached - "HOLY CRAP MATE MY DA GOT US TICKETS FOR THE WORLD CUP!! It's in France but who cares! This is your ticket. Guard it with your life."
Neville - Gryffindor tie clip plus an aquarium tank with the proper environment. Note attached - "With Fang hanging about with us, I thought this would be a nice safe place for Trevor to be in when we're in lessons and not able to watch the lot of them."
Ron - Gryffindor tie clip plus a four leaf clover charm on a leather necklace. Embedded into the charm is an actual four leaf clover from his backyard. Note attached - "While you may or may not believing in luck charms, I figure a clover from the Isles couldn't hurt in your journeys."
Harry - same as Ron's Hermione - same necklace but on an actual chain. Charm is a bit larger then the boy's to fit the Gryffindor emblem on the back. Both gifts are in a box tucked under his bed in hopes that they'll return.
