Is this Geek Squad renewal email a scam?

Very likely. The “Geek Squad renewal” email claims your subscription is auto-renewing for a few hundred dollars and gives a phone number to “cancel” — a fake-invoice scam. There's no real charge; the number connects to scammers who either talk you into remote access to your computer, ask for your card to “refund” you, or trick you into moving money. The invoice look and the toll-free number are the whole hook.

A real Best Buy/Geek Squad charge appears on your card statement and in your Best Buy account, not only in an unexpected email, and support is reached through Best Buy's official website — not a number buried in an invoice. Legit billing emails don't pressure you to call immediately. Don't call the number or open attachments; if there's a link, check it first, and verify any charge in your actual bank statement.
