A couple of these have been posted as deals yet the Asda trade-in thread was in Misc.
Given that Argos probably aren't going to react to price drops as quickly as Gamestation/CEX there could be quite a few of these posted. You could also say it encourages "trading" because people will buy multiple copies for the sole purpose of trading.
Should these be deals or Misc threads?
No strong feelings either way other than these may be a regular occurrence in deals.
