The Premier packs had PREMIER written across the front of them while the retail did not. The Premier boxes were much more sought after due to having far more inserts and also the Border gold seal auto redemption (there were only about 1600 premier boxes off the top of my head).
I have both wrappers, I can scan them up tonight mate if you want.
From memory there were 4 error cards in the Retail edition.
Cards 12 & 13 Geoff Marsh and DamienMartyn & 36 & 37 Cullinan and Donald had the wrong pictures printed on the front of the cards.
This was rectified in the Premier edition.
