Binatone Big Button Mobile phone (for seniors) £34.99 from Makro C & C (need to be a member).
Amazon have it for £53 and Maplin have it for £54.99 but out of stock.
Was looking for one for an older relative thought this might be ideal, but not checked it out though!. I'm amsuming Makro is charging vat at 15% (and not 17.5%).
Phone is not locked.
see in Makro Mail Office, page 13.
Also Duracel plus AA 18 special pack Batteries £2.49 (+ Vat ) not to be mistaken with the 12+6 packs for £5.99 pack!
Note: using image from Amazon, but item from Makro Cash & Carry
