When my receipt says 68 dollars from costco but i paid over 100 dollars. I have receipt and order history. 30 more dollars for delivery..... uber is better... way better... 30 dollars.. and 35 dollars of costco receipt and thru this app i paid 50. So total 100 dollars of purchase from costco, i paid 150 dollars in total. So i am wondering 50dollars more is correct and it is service fee? With the insta express.... im not sure to recommand this app
