Until recently, I was a "Wait for the Trade" guy. Here at my local comic shop in Australia, a $2.99 comic will cost $4.50 - our dollar is on parity with the US but there's the added cost of shipping that the shop needs to cover. Trades were always the cheaper option.
Recently I got an iPad and now I'm a "Wait for the One-Month Price Drop" guy. I can pick up most monthly titles for $1.99 if I stay a month behind in my purchases. This is much cheaper than I'd pay for a trade here in Australia, which means I can afford to buy more monthly titles. Compared to trade release schedules, being a month behind doesn't bother me at all.
