Amazon.co.uk is a great place to shop (cheaper than the high street) and by using this link you help support the site. or check out these recommendations.

Moviegoods.com is the first stop shop for movie posters and although the site is based in the USA this is actually a plus since the exchange rate is so good. Movie posters are great collectibles and the doubled sided teaser posters for popular films are guaranteed to go up in value.
