EDIT: Whole Foods has sued Raise as well as sued or threatened to sue other gift card reselling sites. No site will take Whole Foods currently.
H/T to Esther: Gyft is offering a bonus $20 Whole Foods gift card with a $100 gift card purchase with code WFMWISH, which is 83.33% of the normal price. Limit 3 per household (or while supplies last). Also, earn 5x Ultimate Rewards points when you pay via PayPal with a Chase Ink card. You can try a shopping portal as well but unsure it will work.
