The Sun ones always annoy me. We don't have any of the specified shops within probably 60+miles of here and even further for some. I've collected DVD's from The Mirror, Express, Mail etc and all of them have an option to collect the vouchers and post them off to get the DVD's if you don't have ready access to the specified retailer.
The Sun never does this (NotW used to be the same too), they specified Asda before and there isn't one for donkeys miles either. Do they not realise how much it pees people off to have the offer splashed everywhere and not be able to get it?
