your best bet is ebay , but as far as the syns online goes you HAVE to be a paid up member to access. this is closely guarded by ninjas wielding hifi bars ready to strike. lol
if you need help with a syn value post it over in the syns section and someone will see it.
if it has no free food value then it will be 1 syn per 20 cals.
good luck with your journey and welcome to minimins :welcome2:
