Ozstock Freebies - Are They Really Free?

Okay as per my comment on the latest Ozstock deal

Going there to pick up one of their freebies which has a pickup option, i also note there is a new deal today with a post only option but is free (+ postage) although no pickup.

If i am going there to pick up an item which they have allowed pickup, and i would like todays item aswell then if it is really free, then why can i not pick both items up ??

I dont mind ozstock although kind of gets annoying when you get a couple of the deals and some are pickup others arnt

Update: The guys at Ozstock were nice enough to sell this to me pick up at a resonable price, so i was able to pick up both items. To be frank i am very happy with the result once again Ozstock have turned a skeptical customer around… thanks guys n gals
