Its in Brazilian Reals I think they are called. You can convert with XE.com to see what it costs. I still find them a bit pricey when converted, but you do have to expect a bit more to maintain such an large amount of relatively, and very obscure shirts. I think Subside Sports is bit pricey too, but again, great stock.
Lets have a look at a price of an obscure Jersey I'm interested in as an example.
Palestine Home. Nice looking shirt. I have many Palestinian friends so I'd like to have one.
Price:
R 249.00
Euros 94.80
USD 134
GBP 80
The only other place I've found these shirts so far is at classicfootballshirts.co.uk
Here the price is 50 quid. However they only have the Home shirt not both. But 30 quid is a big difference to me. In CAD that is like 90 vs 144. That is all before shipping.
So I'll save the Brazilian site for last resorts. Even they don't have a Malta shirt
However, upon closer inspection, for some things their prices aren't too bad. But that's only on some things.
