Love the idea of a card shop in Sydney , one thing you could do is consign cards and charge 20% or so this will biuld your stock without much charge to you , also card/ comic surplies , I would be in there for sure , good luck

I think jerseys hats and shoes is a great idea as you don't have to be a card fan to want to go into the shop. Some people may see the jerseys walk in and see cards that they used to collect in the 90's hopefully re-sparking a love they used to have for collecting.
I think there's a market for box breaking recording videos onto YouTube in Australia, similar to what Chris does for cards infinity... Check it out, I always liked going into kikz101 would be cool to have a card store that also had a bit of experience where you can buy hats, shirts, singlets or just sit on a beanbag and watch some old nba games... I would definitely visit and empty my wallet a few times a year...
