Always use a credit card for online shopping — never a debit card. Credit cards give you zero-liability fraud protection, chargeback rights if an item never arrives, and purchase insurance that covers theft and damage for 90 days. A debit card offers none of these protections, and recovering stolen funds from a debit account can take weeks. Beyond security, the right card earns 1.5–5% back on every online purchase. For Amazon and food delivery specifically, the Amex Cobalt at 5x on food categories is unbeatable. For everything else, a flat-rate card like the Rogers World Elite at 1.5% keeps it simple.

Purchase Protection Comparison
Purchase protection is the hidden reason to use a credit card online. If an item is stolen, damaged, or defective within 90 days of purchase, most credit cards will reimburse you up to $1,000–$1,500 per item — no questions asked. Extended warranty doubles the manufacturer warranty by up to one year. And if a merchant refuses a refund, you have the legal right to file a chargeback through your card issuer and get your money back. These protections apply automatically to every purchase without registering or paying extra.
| Card | Purchase Protection | Extended Warranty | Price Protection | Fraud Liability |
|---|---|---|---|---|
| Amex Cobalt | 90 days, $1,000/item | +1 year | No | $0 |
| Amex Platinum | 90 days, $1,500/item | +1 year | 60 days | $0 |

Online Shopping Security Tips
The most important security habit is enabling real-time transaction notifications through your card’s app. You’ll get an instant alert for every charge, which means you can catch unauthorized transactions within minutes rather than weeks. If your card offers virtual card numbers (Capital One, CIBC, and Amex all offer versions of this), use them for one-time purchases at merchants you don’t fully trust. And always check for the HTTPS padlock before entering card details — if it’s not there, don’t buy.
| Tip | Why |
|---|---|
| Use a credit card (never debit) | Fraud protection + chargeback rights |
| Enable transaction notifications | Catch unauthorized charges immediately |
| Use virtual card numbers if available | Limits exposure of your real card number |
| Shop on HTTPS sites only | Encrypted connection protects your data |
| Avoid public Wi-Fi for purchases | Use VPN or cellular data instead |
| Save screenshots of orders | Proof for disputes if needed |
| Check statements monthly | Catch unauthorized charges early |
The Bottom Line
Use a credit card, not a debit card, for every online purchase. The fraud protection and chargeback rights alone justify it. For maximizing rewards, pair an Amex Cobalt (5x on food delivery and online groceries) with a no-fee flat-rate card for everything else. Enable transaction alerts and use virtual card numbers when available.
