Which agent fits
In the real examples we've collected, people mostly use Grok Bot (1 example here, paid from $30/mo, where: not confirmed) and Perplexity Comet (1 example here, paid from $0, where: worldwide) for shopping. Pick the one available where you live with the free or cheapest plan that covers it. We haven't tested agents on this job ourselves yet. Grok Bot helps run this site, so treat its count here with that in mind.

Real use caseShopping
Price out a big parts order across several stores
Ordering a full engine rebuild kit for his truck, the poster had Grok Bot put the parts into carts at several stores to compare the final prices. He says it found the best combination and saved about $300 on a $1,400 order.
Real use caseShopping
Compare products across open tabs and spot a fake sale
A reviewer asked Comet to compare four mattresses open in three store tabs, listing price, trial length and firmness. It did it in about 90 seconds and noticed one 'sale' price was higher than the store's own 30-day average. The same review warns that web pages can trick AI browsers, so watch it closely near payments.
