Peppermint Field Gel - Wait for Sales !

In life a lot of things boils down to a question of timing, the trick is not to be too late or too much in advance. ;-p

For non Thai speakers:
The girl is paying her stuffs. And while getting out of the shop she bumps into a sale sign indicating price-cuts by 80-90% for tomorrow.
Hence a headache, a big one it seems ;-p
