Same here. They sent me a 50% off coupon a while ago. Once I had completed an order the price with all fees was basically still double the in-restaurant price despite 50% off.
My friend did the math and found that her Costco orders were 40% more expensive with IC. It does save her the time of going to the store, which is not trivial (especially with two kids), but 40% is one hell of a markup!
InstaCart’s pricing seems way more reasonable.
