SVP have the Kaleidoscope Overprint 48x CD-Rs in at £9.99. But if you're a part of the SVP/HUKD discount scheme (which is free) then you can get them for just £5.99 for a pack of 100. That's 6p per disc.
Postage, unfortunately, is £4.68 to UK mainland but you can buy upto three packs to spread this cost. Postage doesn't increase with the order, though, and there's plenty of other bargains to be had to make this worthwhile. Don't forget that there's 3% cashback via QuidCo, too.
"These attractive overprinted CDR have been bought back into stock by popular demand and are available in a range of various colours. Each pack of 100 contains discs of the same colour/style."
