I use vpns too for ebay and paypal, i subscribe for those vpns with dedicated ips as those i found to be better than logging into ebay and esp paypal with different ips which is risky as paypal can interpret another ip as someone having hacked into ur acct and can limit ur acct for that.But dont use the same Dedicated IP for 2 ebay or 2 paypal accts, that could lead to linking and limitation/suspension
