The (in)famous Sunday Times Wine Club stamp, the 2nd class self-adhesive coil from the 2010 printing, has recently made a couple of appearances on online auction site eBay.
The first sale, which was for the whole mailshot, complete envelope and contents, sold for what many thought at the time was a too-low price of £56. Now a single example from kiloware has been chased up to £113 by 6 bidders, and another has just started. This doesn't have quite the same spray-on postmark as the STWC one so may be from another mailer. I've been sent a picture of some other examples from kiloware, and while it isn't possible to confirm from the picture that they are all MA10/MRIL I have no reason to believe they are not:
Remember if you see one offered for sale, or find one yourself, that if there are no security slits, this is from the gummed coil, not the self-adhesive. The perforations on vertical sides will be cut, and probably short; those at the top and bottom may be guillotined or torn.
