It depends on how you want to buy. If you're using credit cards, it is advised not to use VPN since your requests go through another private network which might be able to sniff out your details. I am no expert in networking so I'm only sharing my worries over it. It is advised to use the Cookie Method which this extension provides, which is not network in nature, but of application layer.

In the case you are using WebMoney, then there's no choice but to use VPN since some of the choices in reloading only shows up on VPN. This is safe since WebMoney codes are one-time use, and no one can hack you this way. This is my info since I last purchased, but things may have changed, so you may want to check updated guides in Shop/Purchasing
