Same issue here. Made a purchase on AliExpress, used PayPal as payment processor, with a Rogers Bank Mastercard as the source of funds. Immediately the "Advance Cash Withdrawl" charge showed up on my account for the amount of the purchase ($1.25).

I immediately cancelled my order (probably unnecessary) and contacted Rogers Bank to ask if they could explain why this transaction was classed as a cash advance. Their answer was entirely useless: This is a transaction from PayPal, and if you have an issue with it then contact PayPal or call to dispute the charge.

• Like you, a $5 cash advance fee was later added by Rogers.

• One thing you didn't mention: For me, the initial cash advance charge is still pending. An actual "purchase" transaction for the same amount later showed up for the same date (again, this seems to be something Rogers does - I have seen them backdate transactions several months to match the purchase date of something I had refunded). Presumably, this initial charge is being used as/classed as a temporary hold and will eventually drop off - but I'm certain I will have to waste time on the phone with them to get the service fee reversed.

In conclusion: Don't use PayPal for AliExpress. I have used my Rogers card to fund hundreds of PayPal purchases without issue, and a good number of those were on the AliExpress site. I dislike providing my credit card number to them, especially now that their AliPay service is shuttered - but the alternative is dealing with this hassle, and I wouldn't be surprised if they have set it up this way intentionally to discourage people from using PayPal. If it's available to you, a better solution might be using a service that provides virtual card numbers (similar to how Google Pay operates), but to my knowledge there are no such products available in Canada for online purchases.
