Hi from Argentina! Here we unofficially deprecated the AR$10, AR$20 and AR$50 bill, so the smallest one is the AR$100 bill (~US$0.07). Every price include taxes.

What are they selling? Candies one by one? Inside the candy store everything is rounded to a multiple of AR$100. A single candy is AR$100. You many get an offer of 3 candies for AR$200, or 2 small candies for AR$100, or other fancy candies in packages of 13 for AR$1000. Everything else is more expensive, like AR$700 or more, but all multiples of AR$100.

The photocopy shop near my home has a copy for AR$120. They usually sell many copies, so a 20% is relevant. They have a stash of AR$20, but it's probably the only shop nearby. I also collect the AR$20 just to pay the photocopies, just to be nice to avoid finishing their stash and also because I don't know what to do with the AR$20.

I guess a single apple is probably a problem. It cost like AR$400-AR$500 depending on the weight. Someone very smart can learn to choose and apple with the exact weight to get a AR$499 apple and pay AR$400 :) Luckily inflation changes the price so it's difficult to learn. Also AR$499 will be illegaly rounded to AR$500. And most people will buy more than 1 apple, let's say that the total is AR$10,000 and AR$100 is only a 1% that is lower than the spoilage of rotten fruit.
