Top Shopping & Errands use cases
Call local stores to check toy stock
A writer used Gemini's calling feature to phone local stores about a Labubu figure and got text or email summaries of availability, price and hours.
How it went About 40 minutes later she got a message confirming Labubu figures were in stock, with pricing and store hours. The toy was being shipped, and she hadn't received it when she wrote.
Buy products online from a card photo
Musk said Grok Bot bought LEGO from the LEGO website, and that users can drop a credit card photo into chat so it finds the best deal and orders; plans and safeguards weren't specified.
How it went The only result reported is Musk's own LEGO order, with no independent verification. The article says nothing on rollout, plans, countries, or whether shopping is live for everyone.

Hunt high-value Pokémon cards on eBay overnight
An engineer built a Codex agent that browses eBay listings, extracts PSA certificate numbers and cross-references known prices while he sleeps.
How it went It works as his power buyer, surfacing underpriced cards before others see them.
Plan and order a week of groceries with Claude
The poster used Claude on Mac and iOS to plan and order a week of groceries, with partial success, and will keep using it up to the grocery-list step.
How it went Meal planning and list-making worked, but cart-building was only partly successful: Claude could navigate H-E-B and add some items, yet often picked wrong products, got stuck on pages, and needed repeated prompting. The poster said they would keep using it through the grocery-list stage, not full ordering.

Get competing car quotes from dealerships and negotiate a lower price
An agent filled out web forms at 8-10 dealerships and emailed competing quotes against each other, reaching a deal that saved over $4,200 in three days.
How it went After three days he reached a deal and saved over $4,200. He only went to a showroom to sign the paperwork. The source is a secondhand account; Stuyvenberg's own post has the details.

Order family groceries from fridge contents
A parent has Grok Bot check a connected Samsung fridge and order groceries twice a week, hunting discounts, applying codes, and handling pickup timing.
How it went They say it saves substantial time, money, and energy, and in Norway they also have it push the grocery info into Oda while making sure the basket clears the roughly $80 free-delivery threshold. The fridge camera only covers two shelves, so the receipt-based list is needed to fill gaps.

Monitor competitor marketplace prices
The poster uses Grok Bot to check competitor listings and product prices over time, though CAPTCHAs block it on some sites.
How it went It works for ongoing marketplace price checks, but reliability breaks on sites that throw CAPTCHAs, including a mouse-movement puzzle. No performance numbers or savings are given.
Complete online surveys for free stuff
A user had Grok Bot fill out a survey to get free stuff; it has worked once so far.
How it went It worked once: the bot completed the survey and returned the free-coupon link. In comments, another user who tried scaling this to web reward surveys said it was too complicated and used too many tokens to be worth it so far.
