Terra had given each of them 3000 poke, and showed them all the hotel they were going to meet at once it got dark. Josh wasn't very familiar with the currency on the surface, but he assumed 3000 was a lot. He decided to ask Matt, just to be sure. "So, what do you think I could buy with this?"
"It would be more than enough to get you a half-decent TM at Bob and Ed's, but I'm not entirely sure what the prices are around here."
"Let's have a look around, then."

They entered a rather large shop just as Hex was leaving. "Hey, Hex." Josh said as they went inside.
He scanned the shelves, looking for something that was worth spending his money on. There was one shelf lined with TMs, which Josh decided to check first. One in particular caught his eye - Thunderbolt.
"I'll take that Thunderbolt TM, please." Josh said.
The Dragonair behind the counter handed him the yellow disk in exchange for 2000 poke.
Josh lifted the yellow disk with his psychic powers, making it float in front of him. "I can't wait to use this."
They left the shop, with Josh still looking at the TM.
