ARgos have Sony Ericsson K800i (PAYG) for £79.95 for store collection.
Spending a few more minutes and buying £50 Argos vouchers beforehand (with Free £5 voucher) and paying for the handse with £50 vouchers + cash/card will net you another £5 voucher. Cant think of a better K800i deal in High Street for £79.95 with £10 voucher.
