Not long ago, I accidentally landed on a phishing website. I realized I was on the wrong site when I noticed that instead of asking me for my username I was expected to enter my credit/debit card number. Had a look at the URL and saw that the I'd typed in the wrong address. Since it's relatively easy to find yourself giving away your debit/credit card numbers or even passwords of your online accounts to the bad guys, to stay safe download store-specific apps. You'll go straight to the right website each time.
