I have just seen this on a stall in Pantip Plaza today.  I just don't get it.

 

The price tag as shown is 3600Bht on this shoe and various other prices on the rest of the shoes on display but none of them match any of the  "one price" prices as displayed.  Unusually there was nobody around to ask.

Am I missing something, says he rhetorically knowing and expecting some interesting responses, hopefully.

1 pair 1790

2 pairs 1590 each

3 pairs 1490 each
