I tried to order a 2CR5 and got the following from 7dayshop`s website. "Sales of Lithium Batteries at 7dayshop.com have been temporarily stopped As of Monday 14th January 2013, Royal Mail have prohibited Lithium batteries being sent through their postal network. We are currently working on alternative courier postal options for these items and will begin to sell and deliver these items in the UK* as soon as we can. This will, however, mean increased delivery costs for all Lithium batteries. Until the courier options are in place, all Lithium batteries have been removed from our website. 7dayshop.com remains committed to offering the best value in batteries. We're very sorry that legislation outside our control will lead to our customers having to pay more for the delivery of Lithium batteries. 7dayshop.com will still continue to supply Lithium batteries to our customers but we hope you will understand the reasons for the increased delivery charges. When we do start to sell Lithium batteries again, we recommend that you take advantage of our Multi-Buy prices and also order more of our products at the same time to consolidate the increased delivery costs. For more details please see the full announcement below: Lithium Battery Deliveries As of Monday 14th January 2013, to comply with transport legislation, to protect the health, safety and wellbeing of its employees and customers, and ensure that mail in transport does not present a danger to the general public, Royal Mail have prohibited Lithium batteries being sent through their postal network. This means that all sales of Lithium batteries will now have to be delivered using our next-day courier service operated by DPD. The delivery charge for these products will be £7.95 if ordering from Mainland UK or £14.85 if ordering from the Scottish Highlands & Islands, the Isle of Man, the Channel Islands or Northern Ireland. We are not able to deliver Lithium batteries to Eire (ROI) or any other international destination." Whatever RM`s reasons it seems a carp decision to me. edit:looks like amazon still sell thru the post .
