Without getting into an argument and having to explain every action a mod takes or doesn't take...
Had I (or any of the other mods) been aware that the items were for sale concurrently elsewhere the post would have been removed as per rule 5, as there is no room for misinterpretation.
Offloading surplus stock can be a grey area so is to be decided on a post by post basis.
If someone reports a post it (thank you) will be investigated, but again the above was not reported as being on sale elsewhere but was looked into and no action was required as it was deemed, by me anyway, in the spirit of the forum as the OP is not a trader or trying to offload last weeks haul of tat from the car boot.
Selling for a profit by the way is not against the rules.
We try to apply the rules fairly and equally and sometimes we may get it wrong but in the above case (eBay infraction, now remedied not withstanding) no problem.
cheers
