A question about : Free coffee at Harris and Hoole 48 hr expiry limit on voucher via FB
Sorry if this has been posted before, I did search and couldn't find it.
On the Facebook page for Harris and Hoole, a new coffee chain that I think may only be in the south at the moment, there is a tab for a free coffee.
You only have 48 hours to use the voucher (and it is time stamped).
