No it does not mean that. The 15 points is for WRAG only(limited capability for work). To get in the Support group, there are further descriptors that apply, some of which seem similarly worded but are not the same at all. For me the one that comes to mind is mobility - I cannot walk very far at all so I qualify for the 15 points to WRAG, but I also cannot use a wheelchair as I have little upper arm strength to self propel myself along, so I qualify for the Support group straigt away. Otherwise called the imaginary wheelchair test - I kid you not! I also qualify for other things too.

If it's your own stuff, no it's not income but you are supposed to tell DWP about all bank accounts including paypal accounts. therefore it will be deemed part of your capital/savings. If you're not near the £6000 savings cut-off, I wouldn't worry.
However, if you start BUYING stuff, say at carboots, auctions or ebay with the specific purpose of selling on at a profit then technically you're trading and your net profit is income for tax and benefit purposes.
Some declare it, most don't. Some get caught, most don't. If you decide to try and make a few bob, and that's all it'll be, stick to selling 2nd hand goods. It's harder to argue it's your own unwanted stuff if it's sold as part of a brand new job lot!
One additional caveat...CGT may apply if you sell something of your own at a vast profit. But you're talking big numbers to get to that point!
