Is it safe to make online purchase while using vpn?

I want to make purchase on american footlocker from europe and i cant access it without vpn, so is it safe to use my credit card?

It usually depends on the VPN.
If it’s a small name free VPN, it can be quite risky.

But HTTPS usually helps renders those problems obsolete, as either way, HTTPS traffic content is rarely crackable, and most reasonable sites nowadays would have HTTPS.
At most someone would just see the site you’re going to, but not what page, what you’re buying, or what you’re typing.

Aside from the networking part, there might be still abuse prevention measures about using an European credit card in an American online store.

Yes assuming you are buying from a store that take care of security

Short story is.

As long as your browser has that padlock.

You’re certain the PC is virus free.

And the VPN is reasonably well known and trustworthy.

You’re in the clear

This website was accesible without vpn like 2 months ago and i have purchasen product once already.

Im pretty sure company like footlocker does that
