MY PERSONAL ADVICE NEVER TAKE CONTRACTS ONLINE OR OVER THE PHONE OR IN THE BACK OF PAPERS.
99% OF THE TIME THE PHONES ARE NOT BRAND NEW, THEY ARE RECONDITIONED HANDSETS!! CHECK THE SMALL PRINT... THATS WHY DEALS ONLINE/PAPERS/PHONE, YOU GET SLIGHTLY BETTER DEALS.... BUT WHO DO YOU HAVE TO GO TO WHEN YOU GET A PROBLEM ???   THE PHONE!!!!
ALWAYS RENEW / BUYOUT  YOUR CONTRACT VIA  PHONES 4 U STORES!!
