Cheap long distance to Bangkok

I had to call Bangkok last time and got hit with some pretty rough charges on my phone bill. I want to call again and would like a cheaper rate. Anyone know any? How about using calling cards? I’ve never used them, just have a cell phone with a plan. By the way, the calls would be to a cell phone, not home phone. Thanks.

Calling cards would definitely work out cheaper as calling Thailand is more expensive than calling a number of Western countries from Taiwan. I stopped in a Vietnamese restaurant yesterday and saw on a poster on the wall that there are cards available here in Taiwan called BS and GS cards which give you 65 mins to Thailand for 200 or 300 NT(Sorry, I don’t remember the exact price).
