Well that sucks.
When you say “other stores”, do you mean physical stores in your country, or have you tried other online stores like Amazon or eBay (which I believe both support shipping to Chile)?
It’s possible you could get a fairer price through either of those, if you haven’t already. If you can’t figure out what’s going on with your country’s bizarre pricing, that might be your best bet.
Do you know for sure that this doesn’t happen with other toys too?
