See my thread from last week:

In summary,
1. Check out Yellowhead Travel (Sample00's site), iTravel2000 and tripcentral.ca.
2. Find the trip you want.
3. Check for a review on Debbie's
4. If you found it on a site other than Yellowhead (I personally found tripcentral.ca the easiest to use, sorry Sample!), then PM Sample00 with a link to the trip you want and ask if he can provide a better price.
5. 10 minute phone call with him and you're on your way.
