With £5-£7, I am obviously getting myself a milkshake!
And then I pocket the rest for more milkshakes down the road.

...OKAY. Let's say the milkshake was £5, £15 will probably go on the next Initial D omnibus (vol 3-4) book. With £30 spare, I'll save roughly £15 for another Pokemon Eeveelution plush that I need (between Jolteon and Sylveon) and with the last £15 I'll either save it for video games that catch my interest or more shorts in camo patterns because in the summer I need more than one set!!

Of course the big alternative is, if there's a Gargomon plush or statue, then I'm saving the full £50 on that or putting it towards my savings for one! I REALLY want a Gargomon plush and/or statue. Veemon plush too, but Gargomon is priority.
