I just made a trip to Costco to pick up a few things. They had a big sign advertising that you can use Instacart to shop through Costco here now. I decided to compare my receipt to the prices on Instacart.
Here are how the prices came out :
|walnuts||$ 18.99||$ 23.19|
|pecans||$ 12.99||$ 15.69|
|coffee||$ 16.99||$ 18.29|
|jam||$ 6.89||$ 8.49|
|toilet paper||$ 15.99||$ 18.29|
|trash bags||$ 13.99||$ 17.09|
|SUM||$ 85.84||$ 101.04|
As you can see there the prices at Instacart are all higher than in store. Overall the prices are 18% higher via Instacart. This little shopping run took me maybe 20-40 minutes all together in the store and I certainly took my time browsing through Costcos aisles.
Instacart price is $15.20 more than going to the store. Plus assuming you don't have their membership you'd have to pay their $3.99 delivery fee for a total of $19.19 extra
