You're best bet for these is eBay at this point. They typically sell leftover stock on the Club's site, but to guarantee you get them you need to subscribe during the period. Bombardier was during FSS 2, which completed a few months back. FSS 3 should have it's subscription period starting sometime this summer. If you get the subscription it runs about $30 a figure with shipping.
If you're looking for just that Bren gun, however, you could ask around for it. It's been available with a few figures, including the Rise of Cobra Ripcord
