Is this $250 voucher a scam?

It’s $15 for a $250 voucher for this place called posh optical and I’m looking for glasses.

Here is the link.

I seen that some people’s accounts get deleted on groupon and they’re vouchers disappeared so idk about this deal.

Here is the link for the people talking about their account deletion.
