Can I return bought items? And get refunded?
If an item was delivered to you in a damaged state or, god save, got lost along the way - yes, of course, it's either a replacement for no additional cost or a full refund.
Though if for some reason "you cannot find enough love in your heart for this very splecial piece" - ahem, direct quote, well, okay, I'll take it back and refund you the cost of the piece minus cost of shipping there and back.
If that was a custom order - no, I won't take it back. Careful what you wish for, it might come true ;)
