Hi XXXXX,
I hope you're well.
Get $10 off, with no minimum spend. Offer available only to inactive (not shopped in 12 months) or new to eBay Australia.
The unique code will be emailed to shoppers once their account has been validated.
Note that 'SUCCESS' upon submission of email does not mean you've qualified for the $10 off. This merely confirms your entry was received. You'll need to wait until April 24th to see if you've successfully met the guidelines for the offer.
@GregMonarch: Both sellers do not have any condition as such.
The first seller limited the number of offers it's not possible to make another offer.
Even if eBay was to issue another voucher and given it's only valid for 1 week, it seems that there's a good chance it can't be used again under that account because of the 0 feedback.
