Costco in San Marcos (725 Center Dr)

The best price in town ! !

This place is the best. For the two people that want coffee and a restroom, that my friends is a bad idea. Trust me with those long lines, we all want you in and out as fast as possible. No dilly dally. Fill up and go. We would all appreciate it.

Much faster now that additional pumps are open.

Very clean and good prices. It's top tier and the price is good.

Clean and quick considering the low price for the gas. The Cheapest Gas Around.

Great prices. After the warehouse closes is a great time…no waiting.

Several pumps. Use the right lane for fuel once you're on the entrance roadway. Please drive slowly and be courteous to other drivers! 🤗😎

would be nice if a restroom available.

I haven't seen coffee here, but the price for gas here is the lowest Costco that I know of.

As with any Costco, lines are long. Best times are before 8am or after 7pm
