We went to Cancun for vacation in December 2013. The sales person at the retail stores in Mexico including high end stores such as Louis Vuitton and Carolina Herrera told us that we can get 6% tax refund at the airport when we leave Mexico. It is a pretty good saving considering the high price of the products and the sale tax rate in Chicago being 10%. The company which deals with tax refund is called Yvesam. It was only until we arrived at the airport that we were told at the Yvesam booth that we need to pay them 50% of the total refund amount as commission! In addition, it's been more than two months and we still have not received the refund, while the receipt we got at the airport says refund will be made no longer than 40 days! It also says we can check the status of the tax rebate on their website at www.taxfree.com. It was after we came back to Chicago that we found out this website doesn't even exist. We tried to contact Yvesam and found there are a lot of postings saying that they have never received their rebate after three months. It is not clear if the company-Yvesam took the rebate or if the Mexico government didn't issue the refund. However, we would not recommend travelers to buy products that use tax refund as a lure in Mexico. We have traveled in Europe and made purchases at Chanel, Prada, and Louis Vuitton, etc. The tax refund was easy and quick and the commission was only less than 3% (for cash refund only. Credit card refund has no commission). So the lessen we learned: don't buy anything in Mexico, just enjoy the beach.
