I've had to re-do this review since Yelp HQ decided to combine the warehouse listing with the gas listing. Stop doing that!!
Short and simple:
1. You have to be a Costco member to buy gas here, duh!!
2. It's cheaper than other gas stations. Like 20-40ish cents cheaper.
3. There is and always will be a long line. Stop complaining about it.
The end.
