Best part of travelling is the fact that stuff is so much cheaper everywhere else.
Example:
0,5 L Coca Cola in Norway costs 20 NOK.
In Poland it costs 4 NOK. (2 zloty)
Another:
In Norway, a pair of good football (soccer) boots cost 1700 NOK. (283~ USD)
In the US, I bought the same pair of boots for 360 NOK (60 USD)
I can buy 2L Coca Cola for like.. 10 DKK.. + mortgage (3 DKK). Roughly 14,5 NOK I think? (maybe it's a 1,5L but still)
