Just a quick update to let you all know John Lewis & Partners are currently suspended as a merchant, so deals from them won't be allowed on the site (when you go to post a deal and put the URL in, a message should flag up to warn you about this).
The reason for the suspension is repeated self-promotion. We are able to monitor who is posting deals, and could see that its staff were submitting deals, which we don't allow. There have been a number of warnings, and obviously we delete the deals ASAP, but these haven't been heeded.
We hope the suspension period will allow John Lewis to sort their processes out and stop this happening again in future. We'll update this post when the suspension is lifted.
