Can you buy food without a Costco card?

You can buy from the hot deli without a membership, but not groceries.

Can't even get through the door with out a membership

You must have a membership. A Costco gift card will also work. You would need someone with a membership to purchase a gift card for you.

I know you have to pay $50 $100 just to shop at this business

You can go in the exit and get food at the "deli". It is great for a cheap lunch. $1.50 hot dog+drink. Not the healthfood choice, but great in a pinch on the cheap.

Yes you can. Walk through the exit side straight to the food counter. No membership required.

You can buy with a Costco cash card...like the ones members give out as presents and such....if you know of anyone that is a member....you can reload it also

So two conflicting answers...I've seen students from the high school buying lunch, so I think maybe you can.
