Is this a scam?

[niniyogini]

I listed some trainers on eBay and accepted an asking price offer. The buyer then requested I email her directly to confirm the trainers were new and in good condition, which I did (probably a mistake, but I'm new to this).
She then replied saying she was buying them for her cousin and would send £10 extra for postage and another £200 for me to buy a 'Steam' card to include in the package, which she wanted me to post direct to her cousin.
I thought this sounded suspicious and reported the buyer to eBay. I then blocked the buyer on my email.

 My question is what do I do next? Will eBay let me know if this is a scam and the contract void? And can I relist the trainers on eBay? 
Many thanks for any help and advice.

yes its a scam, they got you to answer a question to get your contact Email.

On day 5 you can cancel the transaction as buyer did not pay - they get a strike and you get your fees back.

Sending her your email address was a mistake. I imagine these other requests to send a stream card etc have been sent to you directly by eMail, and not through eBay messages? This means that eBay won't even know what happening, or take any action.

I take it that the buyer hasn't paid? They probably won't, as I doubt they even want the trainers. Biddng was probably just a ruse to try to con a new seller into buying a £200 stream card.

I would just ignore then, wait for four days from the sale, then if they still haven't paid use eBay's new procedure to cancel unpaid items: https://community.ebay.co.uk/t5/Announcements/New-cancel-function-for-unpaid-items/ba-p/6939127

You can also report their actions to eBay here: https://www.ebay.co.uk/help/buying/resolving-issues-sellers/report-issue-seller?id=4022&st=12&pos=1&...

p.s. Having given them your email address, they or others like them may well try further scams. They also have your name and address, through eBay. The combination of this information would enable them to produce convincing personalised email scams. Be vigilant!
