In Costa Rica this is illegal too but going through the hassle of reporting it to the local authorities is a pain and you won't gain much, just annoy the dealership.

Usually the POS rate is around 2% so at the end of the day you'll split it evenly and get a 3% discount. A few years back it was even highter and I bought several home appliances and saved around $100 so it's worth for both parties.

Now imagine people that deal with ranges from 10K to 100K - It's definitely worth it shaving a few bucks here and there
