Instacart - No tax on Costco purchases

Instacart isn't charging any taxes on purchases from Costco. Seems like a bug but might be good for anyone who's looking to make a high-value purchase, like a $2,000 MacBook. You can really end up saving 13% while also keeping all the benefits of purchasing from Costco. Yes, Instacart prices are slightly higher but for large-value items this is going to be a large saving.
