Dipper and Wendy earned a good amount of money! What would be the first way for them to spend?

Personally, as adults, I can imagine that Dipper will insist on saving and desperately needed subjects first. When it comes to Wendy, I'm torn between being more impulsive with saying "C'mon, dude, we can chill and enjoy first. You can save later" and taking Dipper's habit in a hard way.

In younger days, I can expect that while Dipper will save some amounts first, he may fight against his urge to spend his allowance or paychecks from his summer job on his passion projects like exploring the anomalies and such. Wendy can be highly impulsive than Dipper under the same condition, is my guess.

Feel free to imagine it yourself!
