Can I return it?
Yes. You have 14 days from delivery to change your mind, under UK consumer law. If it isn't as described, I'll refund you and pay the return postage. Read the returns policy.
Why is it cheaper here than on eBay or Amazon?
Buying direct cuts out the marketplace fees, so we pass the saving on: our prices here are always at least 10% below our own eBay and Amazon listings.
