I just checked how much the Costco membership costs right now in Mexico, and honestly there are several options depending on what you need. The most basic is the Gold at 600 pesos per year if it's for personal use, or if you want the executive version with 2% cashback on your purchases, it's 1,200 pesos. For those who have a business, there are also options: the regular business membership is 600 pesos and the executive is 1,200. The interesting thing is that all include an additional card at no extra cost, although if you want more people on your account, each additional person costs 300 pesos.

The membership cost is quite justified considering you get access to private label products, exclusive promotions, and services like optical and pharmacy at some locations. Additionally, the membership works at any Costco worldwide, so if you travel, you can continue shopping with the same card. Honestly, if you shop regularly, the membership cost is quickly recovered through discounts, especially if you get the executive for the cashback benefits.
