How frustrating! Paying out the waa-zoo for something can really put a damper on your fun. Budgets matter.
Well, maybe you can find a way in your mind to justify the cost?
1) You are going to NATIONALS... how freaking cool is that?
2) It's money. You will earn more and pay off any debt you may have incurred by shipping the bikes.
3) This is a one in a lifetime chance that a lot of people don't get to do. You know, when I do stuff that I never expected to do... and I spend more money than I should I have... I have NEVER ONCE REGRETTED it. I always look back on the memories fondly and the money I spent seems really irrelevant.
So... good kharma to you! It's worth it! Years from now what you are paying now won't mean a thing but the memories will.
