Grocery sites blocked Grok Bot from building a cart
A parent out for the day found a dinner to make with their daughter and asked Grok Bot to build the grocery cart and show the total first. They say Walmart, Instacart, DoorDash and Amazon all blocked it. Many stores stop agents that browse their site like a person. The more reliable route is an official connection: Instacart's help center lists ChatGPT, Claude, Gemini and Muse as apps that can build a cart you then pay for yourself.
The lesson: Plenty of stores block agents that browse their site. Check for an official app connection first, or have the agent make the list and order it yourself.
Copy this prompt
I want to make [DISH] for [NUMBER] people tonight. Write the ingredient list with amounts, and check what I can skip if I already have [ITEMS AT HOME]. Then give me the list grouped by store aisle so I can paste it into my grocery app. Don't try to log in to any store.
Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.
Watch out for
- Instacart's help center lists ChatGPT, Claude, Gemini and Muse as supported. Grok Bot is not on that list.
- Even with a connection, you confirm the address and pay yourself.

Plan the week's meals and fill the grocery cart
Deciding what's for dinner and writing the grocery list every week takes real time. An agent can plan meals around what your family eats and what's already in the fridge, then build the cart. Here is which agents can actually reach a grocery store, and where you still check and pay.
