The story about buying express train's ticket

I bought express train's tickets for ShinOosaka. As I told before, I'm going to go USJ in this winter vacation. I'm thinking I use the express train on the way to the turning point and I use express bus on return road.

One thing I thought, I didn't realize the price of express train because it was payed by company but it's too expensive! Come to think about it, it was first time to buy express train on my own. To reserve appointed seat, I should form a queue and unfortunately it was crowded during lunchbreak time. Finally shop's clerk said "It's cost 28 thousand yen, please". Oh it was really expensive. I'm sure it's not good to use express train except for work...
