To be honest, it probably won't be worth your time to resell ceramics if your base cost is 34c each. You would be competing in a market segment that contains 39c chips (Venerati) along with a couple of other budget lines. Unless you are willing to run with really small margins (or can significantly lower your costs), there won't be a lot of room for profit after expenses.
If he is planning to sell in Australia the competion isn't that great. Local retailers sell ceramics around $1ea. While everyone here is aware of cheaper and better option available from US retailers the retail options here in OZ are terrible and overpriced.
