Where can I get a reasonably priced PCR test in Tossa De Mar

Hi all,

Thanks for reading.  Could anyone advise where I can get a PCR test and certificate before i fly back home to the UK please.  There seems to be a few in Lloret, but i can't find any in Tossa.  It can be an antigen but that would have to be guaranteed to the standard accepted by the UK authorities.

Many thanks.... any help grateful.
