An email from Gerry, to whom I am grateful for the examples below, highlighted this interesting titbit which may be useful to some of you.
Given that the miles and points earned on Amex cards are generally far higher than those earned on MasterCard and Visa transactions, it is always frustrating to visit an online retailer to find that American Express is not accepted.
In many cases, though, the same retailers will now accept PayPal as a method of payment. And PayPal DOES let you use Amex.
All you need to do is open a PayPal account and link your American Express card to it. (Opening PayPal accounts can be a bit of a faff, because they need to comply with money laundering regulations, but stick with it.)
Next time you pay a retailer such as ebay, Wilkinson, Lily O’Brien, Superdrug, Domino’s Pizza etc who do not accept Amex but do take PayPal, you can now click through to PayPal instead. You don’t even need to have your Amex card to hand, all you need is your PayPal log-in name and password.
There are usually no extra fees for using PayPal either.
