5 reams of basic A4 paper at Amazon. Picture is of 1 ream but the description states there are 2500 sheets/5 reams. Mine arrived yesterday and there are, indeed, 5 reams. There is a marketplace seller selling at £6.17 but I don't know whether the full 5 reams will turn up..... This has been cheaper in the past but still seems an excellent price. Bear in mnd that Amazon's prices often increase once people start to buy - so this is likely to be a short life deal. Works out at £1,38 per ream. Non Prime members will need to add on a delivery charge (exrtra £4.75) or buy 3 packs for free delivery.
