Yes they do
Yes, high quality (Top Tier) and good prices.
Yes they do across the street
Yes, don’t go during lunch time or around 5pm, you will be waiting quite a while
Yes, they have a gas station across the road.
Yup. It's across the parking lot from the Costco building though.
Always buy gas before costco opens. 6AM works great
Yes, look online for locations
Just echoing what everyone else has said so far, they do. The gas line is slightly away from the Costco store (across the street). The line itself can get pretty long to the point where you have a backed up intersection because people are trying to turn from both sides to get into the Costco gas station.
Some locations but not all. You can check the site of interest and it lists it there.
Yes, crowded though
No not at this location
Try to go for gas early or late. Although they move relatively quickly, the lines tend to be very long.
