From what I can see you now have a working site with over 340 voucher codes non of which you have had to add, and at the most will cost you £1 per week which is fully hosted and updated by all of us, a site inwhich is constantly being upgraded with new features and improving daily without any more input needed from you if you don't want to add to anything yourself.
If you do want to add a voucher code all you need to do is select the merchant from your admin area and it will show you all the codes already listed, if you find that code in the list you don't need to add it, if it isn't in the list then you may add it.
I cannot really see the headache, especially when so far its cost you £0 per week.
The duplicate merchants your seeing in the drop down menu is caused by the version of firefox browser you are using.
I have not deleted any voucher codes since reading your post, the last voucher codes I deleted was a while ago due to them having incorrect dates, so your complaint about any out of date voucher codes was dealt with by me before anyone had the chance to complain about them.
I would love to see how much of a better job you can do starting from scratch, then continually having to find, enter and update your codes with no body involved to tell you which codes are incorrect.
Can you please send payment of £49 to
paypal@icodes.co.uk in order for me to keep your domain active, if you no longer require your domain for whatever reason please either confirm it by email, pm or post here
Cheers
