Currys currently seem to have 10% off Nespresso machines... makes the Inissia & Aeroccino £98.99. Seems like a great price to me, only £25 once you take into account the £25 capsule vouchers.
*** Edit *** A few people have mentioned the price being £109.99. You need to use the voucher SBOX10 at the checkout for the 10% discount. Sorry, should have mentioned this at the start but seriously, its in the center of the page when you click through.
