Maybe. You get 30 days and a refund to your card, but the policy doesn’t say who pays return shipping. Worth asking the store before you buy.

Questions.

Where can I use Blink?

In ChatGPT, Gemini, Claude, Grok and any client that supports MCP, through the API in your own product, and in your browser with the Blink extension.

Does Blink buy anything for me?

No. Blink answers questions about a store’s terms and says whether a purchase meets your conditions. Your agent, or you, still decides and checks out.

What can my agent ask through MCP?

Questions about a specific product or store: can it be returned, for how long, at what cost, refunded how, and whether a purchase meets conditions you set.

Do I need an account to use the MCP server?

You connect with the server URL. Heavier or commercial use goes through the API with a key.

Fine print. Finally read.
