I haven't been to Chile but I got this from Wikitravel:
Citizens of four countries must pay a "reciprocity fee" of varying amounts. The fee is USD 131 for American citizens, USD 132 for Canadian citizens, USD 56 for Australian citizens, and USD 15 for Mexican citizens. This fee is equivalent to the amount that country requires for entry visas from Chilean citizens. The fee is only for tourists entering by plane, and the one-time charge is good for the life of your passport. US citizens should have crisp $20 bills or a credit card to pay the $131 fee. Citizens of other countries, such as the UK, do not have to pay a fee.
Only entering by plane? What if you do a land border crossing. I thought the reciprocity fee was assessed at all entry points that offer visa on arrival
