This is a great place to browse unknown titles but the prices are not exactly cheap.

Unassuming shop front on Whitechapel High Street leads to an Aladdin's Cave of blank media goodies at great prices. When I worked in the City, this was my regular place for photo printing paper, usb sticks and memory cards. I only ever dealt with them F2F in the shop, and found the service fine. Judging by comments from other reviewers, the mail order service may not be quite so reliable.
Now that Harvey Buat (in NW8) has closed, this is the best blank media shop in London. Highly recommended.

Friendly helpful staff. Lots of excellent stuff to buy at reasonable prices!
Excellent service although slow on general test wand even slower on SATA drive testing, for this I would recommend the Brixton store.
