I used to be able to bid on items in different eBay accounts, but now it does not seem very easy to do that. It is still possible to use my bidslammer account to switch between bidder accounts?

Hello,
Our service has always been one account uses one eBay Id. However, you can make a second account and switch between them. It does require a logout / login action for each switch.
We can also apply any purchase you make to your other accounts, if you wish.
Thanks for taking the time to write in, please let us know if we can help further.
