Hi, just found a promo at tesco whereby on some selected mobile you will get free delivery plus a £10 voucher. Something like a motorola W377 ends up costing you 19.99, normally these sell anything from 29.99-39.99. Not a brilliant deal, I know, but a decent enough one. Since the £10 is in the form of an e-voucher you can use it, or sell it on.

No need for photo cause if you click on the direct link you'll see images of the phones this offer applies to on their site.
BTW if you go through a sale at first it shows 4.95 for delivery but if you click onto the next page it will state (and show) that delivery IS free.
