eBay is removing sales listings for wristbands for the queue to see the Queen lying-in-state in London.
Sellers were offering the paper coloured bands, which mark mourners' place in the queue as memorabilia.
The bands are marked as non-transferable and do not guarantee entry into Westminster Hall to file past the Queen's coffin.
A spokesperson for the auction website said: These items are against our policies and we are removing them.
A few of the wristbands remained on the site under the header "new listing" yesterday morning but did not link to an active auction or buy-it-now page.
The Guardian has reported, some used wristbands were attracting bids of up to £70,000 before they were removed.
However, it is not known whether the bids were genuine.
