Tips from locals
There is this one and one down MacArthur on the other side of the Santa Ana River. Cheap gas, food and everything else. There is another one in Tustin at The District.
You need a membership card to get in but you can get one at customer service. Membership fees varies. They carry everything. While you shop, there is small food court, optometry, tire center or low price gas.
