Hey there,
I regret I can’t say what would be the cheapest way to return the item you will have to do a bit of shopping for this, however I can advise on your protection as a buyer.
Make sure that you open a not as described case within 45 days of you sending your payment. This means that the once the return of your item has been confirmed a refund can be issued and the seller cannot dispute this.
Also please return using a tracking method as you will need valid tracking to the seller address to be covered.
