Mjollnir

Megingjörð

Járngreipr

Tanngnjóstr

Her necklace

Her cat chariot

A feathered cloak

One of her Valkyries

Gold and amber beyond count

Thor's hammer

To marry Thor

To marry Freya

The hand of Frya - just the hand

Loki

Freyja

Thor

Heimdall

Have Loki speak for him

Have Loki cast a spell on him to make his voice sound more feminine

Just tell the giants that the price of Freyja's beauty is her ugly voice

Have him try to speak in a higher voice and hope the giants won't notice

Loki says that Freya hasn't eaten for eight days and nights

Loki says that Freya wants to impress the giants to show she can hold her own with their culture

It's not (just a plot hole in the story)

Loki doesn't explain, he just shrugs

Thor's hammer

The necklace of the Brisings

Her weight in gold (which turned into a bad deal since it was really Thor's weight)

Nothing - to be married to Thrym IS the gift.

He escapes with Thor's hammer

He escapes, but leaves Thor's hammer

He makes a deal with Loki to stop Thor from killing everyone

He gets killed along with the rest of the giants in attendance
